Hi does it work in a crosman shockwave nitro piston and does it have all the seals
Yes It will work.We do not have any instructions.
On the shaft (the black part) of the original BT5M22-00-1A, there is a metal o-ring which I guess is necessary in order to maintain a constant gap between the piston and the gas spring. However, this o-ring is not apparent in the picture of the advertised CR Nitro Piston. Any explanation for that?
For that information ciontact Crosman.
I do have the Crosman F11 in .22, canadian 495 fps max version. The rifle comes with the BT5M22-00-1A gaz spring and a 190 mm piston (there is no hole in it). If I ONLY replace the gas spring, what can I realistically expect in terms of fps with standard 14gr pellets?
If the upgraded piston fits, You will get 750-800 FPS.
Hi I recently purchased a used Benjamin trail np2 and I was wondering which piston seal it uses. I have a crs5177-012 on hand can you inform me please.
That information would have to come from Crosman.
Was wondering if the BT9M will work with a Crossman Fire nitro piston. It's running the smaller piston from factory.
Yes it will but you need to be sure you don't already have it. If you have the BT5 spring then this will bump power and it may exceed the 500fps CA limit. Fyi they usually use a longer piston for CA guns. The spring itself is basically the same size. So be sure you use the correct nomenclature or it gets confusing. Crosman says "Nitro Piston" because it sounds cool, but in their parts list it has the correct names. The part sold here is a spring, not a piston.
What do I need for this ram including the back guide? Or it's part number?
If you're converting a typical Crosman coil spring gun to gas spring it's pretty easy to do and no additional parts are needed. You do have to modify one part, but it would be much easier to just let me send the info with detailed pix and arrows etc. chevota at hotmail and tell me what gun it is and remind me what you're doing to it and I'll send a generic info pkg
We do not have parts for Benjamin/Crosman breakbarrels. There are parts diagrams on Crosman's website.
Will this fit a Benjamin trail np model number bt1k77snp , I think part number is bt9m22-00-5a, and is there any modifications needed to fit this !
Yes this is the spring for that model gun and a direct replacement for yours, no changes needed. This is NOT the NP2 spring. PA is just trying to cash in on selling this much more expensive spring which is weaker than the actual NP2 spring. This spring may fit in an NP2 but you will lose power and $ because the correct NP2 spring is ~$8 from Crosman.
If your Trail model is the NP2 .Yes it will fit. We do not work on Crosman/Benjamin breakbarrel guns. This would be a question for Crosman.
Sorry my PC is not working correctly. I bought a nitro ram like this one here. But with no back spring guide, or top plate either. So where can these parts be bought? Mike M... :)
Any parts would be model specific and gotten thru Crosman.
I just purchased Benjamin Trail np2 elite. i would like to know what gas ram to put in her to bring her up to todays specs, or just to wake up the beast.
This is not the spring for that gun, but what do you mean by bringing it up to today's specs? It's the latest and greatest (according to Crosman) gun they have. Or maybe your spring has leaked, in that case you need to call Crosman and ask for part NP214-012 which is the oem full power NP2 spring. It was $7.77 when I last bought it a few years ago. If it's a new gun they might just give it to you. Other than that you can tune it which will net some power, but odds are you won't notice w/o a crony.
We do not work on Benjamin gas piston guns. Crosman will have replacement parts but we do not know of any more powerful replacements.
What Nitro Piston wold work in my Crosman Quest 1000 ? My E-Mail: [email protected]
You will have to contact Crosman for that information.
i bought a benjamin steel eagle that's really doing LOW fps. what nitro piston will work for this rifle??
That gun is an NP2 so you need part # NP214-012 which is available direct from Crosman. It's ~$8 + $4 flat rate shipping. I'd also get a new main seal or two # CRS5177-012 which are ~$2ea. They don't have an online system for parts, you have to call them. My guess is your spring has leaked but if your breach fell out it'll do that too. That's just an O-ring, I think size -109.
We do not have a replacement gas piston for Steel Eagle. You would have to contact Crosman for parts or service.
I have a BT5M77-00-2 gas spring for a .177 which is realy weak, it can't even punch trough an empty plastic botle of soda. What can I use to get my rifle more punch ?
I've explained the how-to on doing what you want in various older posts here. As long as you're aware of legal aspect, go for it.
We can not tell you what will replace your present gas piston. This unit will not fit your gun.
my piston part# is bt5 m22 snp will this piston be a full power direct replacement?
Yes this BT9 spring is full power and it'll fit. You may also have a longer piston which cuts power to meet the 500fps max. The full power piston is 150mm long. Another method they use is drilling a hole in the end of the piston, so take a look-c. The hole can be filled and a long piston cut down. Of course there's the whole legal thing which I assume you know about? Fyi, if you have a full power piston w/o a hole and your BT5 spring it makes for a very nice shooter in 177, but still slow in 22. Just a thought to try before spending the $ on a spring.
No. This gas piston only fits the rifles listed.
I own a Benjamin Trail NPXL 25cal. I found this item of yours on EBAY (Item Code: CR-BT9M22-00-5A [CR Nitro Piston, Fits Select...] I would like to knoe what the FPS are, As well as what the most powereful one that is compatable with what I hav
As Mark mentioned it's a Crosman direct part. The part # is BT1500-00-2 It's the only spring for it that I'm aware of and it's full power. If you did find an aftermarket one that fits I doubt it would be more powerful. The .25 cal gun is a bit slow since the pellet is so heavy, so about 700-725fps using a std 25gr pellet. If you switch to .22 using a 14.3gr pellet it'll be 850 to over 900. Mine is 940 but I tuned it. The only thing different about a .22 gun is the barrel, which were <$16 from Crosman last I checked.
This will not fit the NPXL. All you can do is get a replacement gas piston from Crosman.
Will this fit in a crosman fire nitro.177 from Canada
It is the correct fit but it may be stronger than the one you have. Best way to figure it out is to remove your spring and check the part #. The spring sold here is a BT9, meaning the first digits of the part # are BT9 and it means it's full power. So if yours starts with BT9 then you're good. If you have a BT5, which is weaker, then this one will no doubt push you over the legal Canadian limit. My guess is you have a BT9 because they are far more likely to leak, which I'm guessing is why you're looking for a new one. That or you have a BT5 and simply want more power. Both springs are available from The Gravel Agency, but PA only sells the BT9.
Would like to confirm, will this fit the Benjamin Trail NP, ( the first Np), not the XL or NP2?
Yes, this is it. You can verify by getting the parts .pdf here: http://tinyurl.com/Crosman-Parts It's likely easier to buy it thru the Gravel Agency since you may get charged misc bs fees for US shipments that can make it not worth it. Look for part # BT9M22-00-5A. That's the full power spring btw. The low power is BT5M22-00-1.
It might. Contact Crosman for that info.
Will this Nitro piston fit and increase the power of my Benjamin Jim Shockey Steel Eagle in .22? The piston that is in the Steel Eagle now is a 6-NP214-012 201507. Also, have you tried to plug the hole in the piston with JB weld?
Well, it may fit in there, and if it did it will make more power. However, the correct spring you're after is NP214-012 (the "6-" designates it as a low power). The NP214-012 is stronger than this spring and much cheaper at ~$17CA from a place like the Gravel Agency. Yes you can plug the hole with JB, just make sure you do a good job b/c the pressure is very high in there. You can write me at chevota at hotmail and I'll send you some info on that along with other tuning info to get the most from that gun.
This will not fill the Steel Eagle.
i have 2 umarex gas piston rifles .177 i would like to upgrade the gas springs as they are very weak. will these fit ? If not do you know what might ?. Thanks in advance
So you have <500fps models? Not sure they'd fit but you can pull yours out and measure to see how far off they are from this one, then decide. I assume you know the legalities of putting a stronger spring in, which I don't care about but I don't want you getting in trouble. This springs dimensions are: ~260mm oal. Body ~150 x 18.12mm. Shaft ~111 x 10mm. If it doesn't fit I think it'll likely be because it's a bit long for your gun. If so the NP2 spring is ~6mm shorter: The NP2 spring is: ~254 oal. Body ~146 x 18.1. Shaft ~108 x 8mm. The NP2 spring is stronger and much cheaper at ~$8-9US or ~$17 Canadian from The Gravel Agency, part # NP214-012 There's lots of info on the forum airgunforum.ca/forums, and I'm there too once in a while
can this use for Crosman TR77NPS
Yes, this is the correct spring for that gun. If you'd like to verify you can go here: http://tinyurl.com/Crosman-Parts look up your gun and download the parts diagram
how to increase the power of my crosman venom nitro piston rusk.22, at 1000-1200 fps. which is currently 495 fps.
As mentioned it's not possible in 22. You can break 800 with the lightest pellets but that's it. If you really want that speed you can switch to 177 by buying a 177 barrel for it from The Gravel Agency, then 1000 is easy and you can even break 1300 with light alloy pellets. There's no advantage to that speed for normal use, but it's fun to shoot things at close range, and you can even shoot a hole in a quarter. It's considered best to not exceed 900fps, which is do to aerodynamic drag which skyrockets after 900fps on up to ~1150 or so. So shooting at say 1200 like you want means the pell will slow down so fast it's only good at very short distances. I think up to 1000 isn't too bad, but 900 is better. So the key, imo, is to make the gun as powerful as possible, then use heavier pellets to bring the speed down, like 10.5gr. Then you have power and correct speed. At least with full power you can play with different pell weights and decide for yourself. I usually use 8.44gr which break 1000, and 10.5 is just under 900. In 22 you have opposite problem and you'll never see those speeds, so best to use pellets no heavier than 14.3gr, which will likely be ~750fps, maybe 770 if you're lucky. Even the magnum springers like the Trail XL can only do 1000 in 22 if the lightest pellets are used, but again it's not ideal so best to use 14.3gr which will give you ~900-940fps if the gun is making max power. I say max power because the full power Venom and XL do not generally make the power/speeds I mentioned, you have to take the gun apart and tinker, aka tune it. So take your gun apart and figure out what was done to reduce power, and undo it, which I've described in misc posts below. Depending on what they did it could cost nothing to fix it, just some work on your part. Or it may require parts, and if you don't do any work yourself and choose to buy said parts, it could cost ~$100CA. The 177 barrel would be another $32CA. Lots of info on airgunforum.ca under Mods/Repair
Hello, I have a crosman venom rusk .22 and I would like to increase the fps to 1000 or 1200 fps, which model of piston must be taken.Thanks
Mark: Yet, ironically, you don't carry the NP2 spring but claim this spring fits it. Anyone following the guidance of PA by putting this spring in the NP2 will pay >5x the price of the correct spring from Crosman, and suffer a major power loss because this spring is weaker than the NP2 spring. PA is aware of this because I told them (Mathew Z, whoever that is), but they don't care. Profits first, even if you screw the customer...
You won't get that from a 22 but if you meant you want to convert a <500fps CA gun to full power then I've noted how in some replies below. You may already have this spring, so first thing is to take it apart and find out how they reduced power...
We do not have that gas piston. you would have to contact Crosman.
I have read the entire string of q+a's and they don't address the Crosman ELS22 or RNP22. I know that Crosman discontinued these models several years ago, can't really say why, but I have an ELS22 which needs the gas piston. I ordered one from Australia which came in much longer than the existing one. Crosman does not handle anything for this model so may I ask what product I should order?
It's part # ELS-012 but my guess is Crosman has ran out? You can try the NP2 spring # NP214-012, but it's weaker and longer. Here's some specs for the springs: NPSS, RNP and misc others of same base model: ~236mm oal. Body ~136 x 18.12. Shaft ~100.5 x 8mm. NP2: ~254mm oal. Body ~146 x 18.1. Shaft ~108 x 8mm. The B18 spring sold here is ~260mm oal. Body ~150 x 18.12mm. Shaft ~111 x 10mm. So as you can see the body is 10mm longer, but it may still fit with min mods? . If the old spring has simply leaked out over time I suppose you could recharge it, but that's a bit much to get into here; [email protected] and I'll explain. Lastly you could mod an NP2 spring by cutting the body down and tig welding it back together. I guess it depends on how much you want the gun? Btw the NP2 is based on your gun, so the NP2 is basically an RNP magnum due to extra stroke. Plus they have some useless (imo) bells and whistles, and lies to help sales.
We do not have any information that this Gas piston will fit any other guns than those listed.
Will this fit Benjamin Titan NP .22?
Yes; This gas piston fits The Benjamin Titan GP nitro piston air rifle.
Hello 1st question, is this the nitro piston 2, it looks like the original nitro piston not the upgraded version ? 2nd - if its the NP2 would it fit in my Benjamin legacy jim shockey 22? it came w/ the original piston few years ago but Im looking to upgrade to the stronger NP2? Thank you very much.....
The NP2 piston will not fit your gun, but even if it did I don't see the point. The NP2 spring can be made to fit if you want. The confusion is Crosman started calling the spring "piston", probably because it sounds cooler. So, the NP2 spring is # NP214-012 and available from direct from Crosman. It was $7.77US last I checked a few yrs ago. The problem is that spring is a bit strong for your gun. It's certainly doable but I consider the original spring for this gun to be a bit much, so the NP2 spring is simply more so. Not a big deal, and since they're not too expensive it may be worth checking out so you can decide for yourself. I will say I would not try it unless you tune the gun, which tames the violence of the shot cycle to help counter the added violence the stronger spring will give. The low power NP2 spring (6-NP214-012) for the UK and Canada is a better choice for many people. It will net easier cocking, and thanks to a less violent shot cycle it'll be quieter, smoother shooting, more accurate and much less stressful on the scope. Power will be less of course, but many consider it worth it, usually people who just plink and/or target shoot. If you want max power pass on that. Or, if like me, consider a B18 (your gun) in .22 to be too slow already so any more loss in fps is not ok. The weaker spring in a .177 is a much nicer combo... You can of course get another B18 spring, like the one sold here, if yours has leaked. Problem is the next one may simply leak too. All mine have leaked, and I'm not even sure I've ever had one with full pressure. I've heard people are having better luck lately so maybe they fixed the problem? I'm simply unwilling to buy any more of these springs to find out. The NP2 springs have been holding up substantially better. So up to you which one to get, but considering the price I'd get both NP2 springs, like I did. Fyi the NP2 spring is ~6mm shorter so you have to shim it about that much or you will no doubt ruin the spring. The shim needed varies with each gun but basically shim it so you have ~3-4mm of preload, meaning you have to compress it that much to get the gun back together. You can email me at chevota at hotmail if you need more details on that, but either way I'll send you (or anyone) my tuning info to squeeze the most power and overall performance from it, regardless of what spring you use. The tuning will net more power than anything so I'd consider tuning more important than the spring, assuming yours hasn't leaked too much. If you do order a new spring, from here or Crosman, be sure to get a new main seal, or two; # B18-04-1A
I was given a Crosman Fire NP 495 air rifle and want to upgrade it to a higher velocity. How would I go about this (I do have a PAL)
You need to find out what they did to your gun to detune it, then undo it. A longer piston is very common, but so is a weaker spring and some have a hole in the piston. The full power piston is 150mm long, so if yours is 170+ then you need to either cut it down or buy a new one which is $pendy. The full power gas spring part # starts with BT9, the typical low power CA spring starts w/ BT5. Holes simply need to be plugged, but it sees a lot of pressure so do a good job. You can try; airgunforum.ca/forums/ and search for my name b/c I've posted pix of how to cut/mod the piston etc in there somewhere. If you have both a long piston and weak spring it'll work pretty good just shortening the piston, then you can decide if you want to spend the $ on a spring. Up to you...
We have no upgrade parts for the Crosman fire NP.
Will this part fit my Crosman Phantom NP .22 ? Wishing I could find a NP2 for a upgrade from 950 fps to 1100 fps /alloy !
If the part # for you gun does NOT end with an "A", then yes it'll fit, but it also what your gun came with so no gains. Another way to know A vs not is to measure the receiver, aka compression tube. If the tube is ~30mm OD then this is the spring. The "A" model, and misc other Crosman guns with a tube ~33mm use a different spring. You won't be getting 1100 no matter what, and 950 is usually only reached with the lightest pellets and luck or a tune. Using a normal 14.3gr pellet you can expect ~700 +-50, and 750+ if tuned, usually 750-770 but I hit 800 once. If you want details on tuning, or some alternate power ideas; chevota at hotmail and I'll send. Just explain mention the above and what you want.
i have a break barrel spring crossman vantage .177 cal air rifle with spring im willing to add a nitro piston need to know is it possible or not?
Yes it is. There are two ways to do it; my way and the wrong way. Kidding, but people usually prefer my way. My way requires no additional parts and is not hard to do. The other common way either costs a lot more or a little more + more work. Totally up to you and I can send you the how-to for both ways. chevota hotmail and remind me of who you were and what you wanted and I'll send this and a ton of other info you can use
hello there, would this fit my crossman nitro venom .22 as mine is only putting out 8.8ftlb and would like it higher than that and if so what sort of power would give me in it ?? many thanks harry
I have one exceptional Crosman B18 that broke the 20ftlb mark after tuning, but normally expect 15-18. The problem in the UK is you have a legal limit so they likely have a BT6 spring in it. Buying this BT9 spring means it'll be FAC.
Yes it should fit. Typically, in a .22 caliber gun this puts out a little over 20 FPE
Can assemble with benjamin trail model np xl
The XL takes spring # BT1500-00-2 that I believe is only available only from Crosman. Call them to order.
I would like to know if your Nitro Piston fits on a .22 Benjamin Classic 33000 Jean
Ok, then the answer is still yes so you have to decide if it's better/cheaper to buy from PA or a Canadian place like the Gravel Agency. I hear horror stories about some fee/tax when buying from the US, but apparently you won't know until UPS knocks on your door. Gravel's price should be ~$52.
No, I do not have a spring, just a nitro piston and a tube and the piston goes inside
Yes but I assume yours now has a coil spring? You can convert it to accept this spring at no cost, just a little work. I'd stick with the coil spring which are far more reliable, easier to cock, much cheaper and less work, but up to you. You can email me at chevota at hotmail and I'll send the how-to convert the gun, which also includes how to make a coil spring as smooth and quiet as a nitro thus making the nitro pointless.
I have a Canadiam version of the Benjamin Trail no all weather (495fps), I was wondering if this would fit it?
Some CA guns used the full power spring, some a low power. I can tell by feel but otherwise you just have to take it apart. The part # is on the spring, full power # starts with BT9, low power are usually BT5, maybe BT6. Other mods to reduce power are a hole in the piston or a longer piston. The full power piston is ~150mm long, longer ones can be cut down to 150 and holes can be plugged. Don't discard the low power spring, it makes for a nice shooting gun once the other fixes are done. You or someone may want it. And if you had a low power spring then this may put you into PAL territory, same with the other mods. If you want a new low power spring then buy from The Gravel Agency in CA which carries all the parts. The BT5 spring doesn't have nearly the failure rate as this one, so if yours leaked I think you have the BT9.
It should, but I would recommend calling Crosman to confirm first just to make sure there aren't other parts needed
Will this work on benjamin varmint .22
The spring is what is sold on this page, it's simply a pneumatic spring that takes the place of the coil spring. The piston is, well, the piston, and if you saw one you'd see how it's very similar to the piston in a car engine. I think Crosman calls it a nitro piston b/c it sounds cooler, and cooler sells guns. It could also, partially, be from what I believe is the original gas spring/piston made by Theoben, which the piston was actually the main part of the spring. Theoben didn't use N2 so they didn't call it a nitro piston, but it was more or less a gas piston. So in short, keep in mind that all these cheaper airguns are all about marketing. They are, imo, in a marketing war with each other. So any little thing/change they make is often not an actual improvement, but it will be touted as the coolest must have thing to get people to buy their gun. Take fps and ftlbs power for example, which is king in marketing these things. They don't just brag about it, they flat out lie about the numbers to stay ahead of the competition. Like this Gamo ad about how quiet their Whisper gun is, which is also a flat out lie: http://tinyurl.com/zyx9euj If you want to see the piston vs the spring, go to http://tinyurl.com/Crosman-Parts and get the parts list.pdf for a gun like the Titan, or Optimus for a coil gun. They're simple sketches so not great, otherwise try google images or some airgun forums. I have pix if you'd like, good ones too. chevota at hotmail and I'll send 'em.
Hello Chevota, Im not sure who you are, Im new here but you seem to be very knowledgeable, I have a question for you & Im also curious why you call a piston a spring, or am I seeing a piston in the listing by accident & this is suppose to be info about a Spring? Thnx
Yes, this is the exact spring that comes with it from the factory
Will this piston fit my crosman vantage .177. I want to increase it from 495 fps
If it has a gas spring now then see the reply I wrote to Devon above. If it has a coil spring then you can either buy a full power coil or convert it to gas spring. Either way I have detailed info in a tuning package if you want; chevota at hotmail and I'll send it
I have a Benjamin charger NP model 7-BCNP7SX sku 28478 14987 which is 495fps. I want to upgrade to the 1200fps Benjamin charger NP model 9-BCNP7SX.

See other replies from me which should answer this
I have a crosman fire nitro rifle, Canadian version. It is a 495fps and I would like to upgrade the fire power as mutch as possible. Can I simply order a new piston and replace it with the one in the gun.
See other replies from me which should answer this
Hi, I have a crosman fire nitro rifle, Canadian version. It is a 495fps and I would like to upgrade the fire power as mutch as possible without damaging too mutch the rifle of course. I now have a bt5m77-00-2 piston and have sealed the small home in the piston. Would this piston fit and upgrade the fire power. Thanks!
It should bring it up to full power, but only if your piston is 150mm long. Many guns have longer, like 175-190 or so which reduces power. I think they only put holes in the 150 so I think you're good? There's some Q&A a few posts down "kyle from Canada" that may help. Note the nice power he netted.
good morning, this piston is for the benjamin trail np xl?
Almost forgot, the oem main seal on Crosman/Benj guns are usually damaged so I suggest getting a new one. The design of the XL also sucks so don't buy an oem, instead get this one: Piston Seal, Fits Walther Falcon... I says it's for another gun but trust me it's the hot ticket for the XL and will net free power, shoot smoother and likely more accurate due to how it alters the way the gun works. Weird I know but too much to explain the details here.
No, you need part # BT1500-00-2 which I believe is only available direct from Crosman. A few posts down I gave a link to parts if you want to get the diagram, then you simply call them and order it but they only ship within the US. Canadians can get it from the middleman The Gravel Agency which may ship to other countries? Other than that I'd google or ask Crosman for authorized Crosman repair facilities near you.
Which nitro piston will fit my crosman phantom.22 Springer and do you ship to Canada
As long as the Phantoms part # doesn't end in with an "A" it'll fit. If it came with a coil spring then it'll require some work to make it fit. To be honest I think the coil is more reliable, and if properly modded it's as smooth and quiet, plus easier to cock. So if you want to try that first I can explain in detail. If you want to put a nitro into a coil gun I can explain that too. Either mod is free (excluding buying the nitro spring), just need some basic tools and goodies. chevota at hotmail and I'll send the complete info pkg which has lots of other stuff too.
Will this fit the Benjamin Summit NPT air rifle ?
This is for the B18/B19 Crosman or Benjamin, not the Trail XL or Trail NP2. They made a B18 Benjamin Summit and Summit NP2 so it can be confusing. Optionally you can measure your compression tube (the main tube body), if it's~30mm this is your spring, if it's ~33mm then you need one of three other types of springs. If you have the NP2 I'd also buy a new main seal # CRS5177-012. If you have a B18 then I'd get that main seal # B18-04-1A. Reason being the oem seal is usually trashed, so since it's apart for the spring....
Is this a full power nitro piston or the 12 ft lbs one? can anyone please please provide a link to a full power nitro piston for my trail np if this is not the correct one. Many thanks
Yes this is the full power spring. The part # starts with BT9, the typical lower power is BT5. If you have a Canadian gun then it will likely have another mod to reduce power, usually a longer piston or a hole in it. If UK then you likely just have the weaker spring, BT5 or maybe BT6. Note for everyone; this is for the B18/B19 Crosman or Benjamin, not the Trail XL or Trail NP2.
Hello. I would like to know if it fits on a MTR77 (1200 fps)??? I need it. please and thank you!
Yes it does. Fyi you can also go here: tinyurl.com/Crosman-Parts and plug in your model to get a parts diagram in .pdf. Then compare to the PA part # which will be the same but with a "CR-" in front which they do on Crosman parts.
Hello Mr Chevota, is this part (CR Nitro Piston) suitable for my Remington nitro piston .177 ? ( item number REM-RNP77) Tks for your time !
No, you need part # ELS-012 which is I believe is only available direct from Crosman. I'd also buy a new main seal # CRS5177-012. Email me @ chevota at hotmail and remind me of this b/c I have some other RNP info to give you, plus I have a question for you
So i own a crossmam benjamin trail np all weather 495fps (canadian version) and i bought this NITRO PISTON RAM 800fps (american version) and i cut down my ram to 150mm drilled a squar hole in the top so it catches and i bought a PROchrony from amazon for messurments and im getting pretty satisfying 750-770 fps with .22 14gr pellets ... MR CHEVOTA sent me all the right blueprints for the ram mod and trigger mod through email. He was deffenitly a great help *5stars* for for pyramydair and MR CHEVOTA
That velocity is good so you did it right :)
Hey i have an detuned banjamin trail np all weather (black) nitro piston air rifle .... i deffenity have the detuned nitro piston iv read lots of ur comments so i ant trying to ask the same questions .. and on my gas ram the 3rd number on the item number is a 5 (low) not at 9 (high) thats how i know and why i bought this replacement ... now iv read that i will have to cut down that piston to get it at its full compassity can i get ur email for the blueprints on the cutting sizes and how it should be cut .... please and thank you
chevota at hotmail. I also posted it on the airgunforum(dot)ca forum somewhere, but the info I send has lots of other cool stuff you can do so better to email.
Mr Chevota.. id love to speak with you more about the NP2 trail .22... is there an easier way to do so than here by chance?
chevota at hotmail Fyi this spring is not for the NP2. The body of this one is ~1/4" longer so it'll likely bind, but if it did fit, or you made it fit, there would be a bit of a power loss since it's weaker. It's also much more expensive than the NP2 spring which I believe is only available direct from Crosman for ~$8. Part # NP214-012. The NP2 main seal is CRS5177-012 and imo everyone should get one.
Hi,will this fit my Edgar Brothers model 60?
I would say not a chance, or at least it won't drop in, but I suppose with some work there's a long shot it'll be possible. It's likely too strong for that gun, plus the price is high and reliability low so I'd pass. There's lots of regular coil springs for sale, various sizes/strengths so that's what I'd do.
bonjour,pouvez vous me donner la longueur du piston ouvert.merci beaucoup.
~260mm oal. Body ~150mm x 18.12mm. Shaft ~111 x 10mm.
Hello, does this fit Benjamin super streak .22? Not sure but i think that model number is B1122BTM Regards, Ivan
The Super Streak is a magnum so it's longer overall, inside and out. It's also a coil spring gun. If you wanted to convert it to nitro then you need the longer Trail XL spring BT1500-00-2, which I believe is only available direct from Crosman and I think is ~$30? It would not drop in, you'd need to mod the gun a bit to make it work. I've never done that gun but I have done the std power version of it and I can send you info if you want. I'd just keep the coil spring and tune it, which if done right will be as quiet and smooth as the nitro. chevota at hotmail if you want info on that too.
Is this the correct replacement for my Benjamin Titan NP model # BW8M22NP?
Yes! You can verify by checking the parts list for that gun, then comparing it to the Pyramid part #. PA puts a "CR" in front, I assume for Crosman, but the BT9M22... is what you want and hopefully the latest spring (ending in "A") will last longer before leaking.
Hi. Thank you for all the great feed back! you guys are awesome! I have a .22 break barrel Benjamin legacy air rifle Canadian cheap 495 fps restricted version. It does not have a hole or a spring in it, all It has is this CR nitro piston in it. I would like to get more power out of it. Will this alone help get me more power or do i need to do other mods to it? Do i need to get other parts change or buy something else? Please help me out. Thank you!
You will need to either cut your piston down to 150mm (yours is likely 170), or buy the 150mm version which is ~$35CA. You probably already have this spring, which has the part # in it. If the third digit is a 9 it's full power, if a 5 it's low. Or you can measure cocking effort, which is ~ 30 and 20 respectively. I have pix and measurement details on cutting the piston; chevota at hotmail, or you can check airgunforum.ca. And be aware of the PAL needed, or be an outlaw, your choice ;)
I have the Benjamin Trail NP pistol. It is the Canadian version which is restricted to 495FPS. I am wondering which piston I could use in the NP pistol to upgrade its velocity?
Well, from what I understand you need an RPAL to legally do that, and if you go thru all that trouble I doubt a Trail pistol would be an adequate reward.... But if you want to, or are willing to do it w/o the legal stuff and be a felon, then I'd take the gun apart and see what exactly they did to it to reduce power. If you need to buy any parts you might not be able to get them shipped to CA at all. My guess is they simply drilled a hole in the piston, or made a longer piston for it. If the piston is normal then I'd assume the spring is weaker.
Hi! Just bought the Benjiman Jim Shockey Steel Eagle .22. Any thoughts on it? I also have the Benjiman .22 classic. How do the compare? Classic is a springer and the Eagle is a NP2. Thanks!
I have a Canadian/ restricted version of a. 22 bengimin trail np. I'm looking to upgrade to the high power nitro piston. Is this what I need
See what I wrote to Frank a few above
Which one is for piston for np xl. Where can I order it
The only place I know is direct from Crosman, # BT1500-00-2, which is actually the spring, the piston is a different part but check the parts list if uncertain. The spring should be ~$30 +$4 ship. Btw I'd get this too; Piston Seal, Fits Walther Falcon..., it's not for the XL but the oem XL seal sux and this is way better and worth up to 10% more power, less scope stress and slightly quieter.. Just be wary not to damage it during install, smooth all those sharp edges inside that cut up the oem seal.
Hello there, unlike most, I need to reduce the power of my crosman nitro piston break barrel guns, I am a backyard shooter, they are way too powerful and way too noisy,,,any idea there? thanks.
Spring # BT5M22-00-1 is the low power version and only available from Crosman as far as I know, and is $26. It's ~2/3rds as strong and helps a lot to tame the gun. You can also buy a suppressor barrel from a Trail or Regal, which I almost always do. I also tune the guns which tames them as well, and heavier pellets help too. You can even convert to coil spring to make them even quieter, which sounds incorrect but it's not. Write me at chevota at hotmail if you want details on any of the aforementioned.
Can I use this to mod crosman tr77 nps
If your TR77 is an NPS then it should already have this same spring in it. I see you're from Canada, in that case I assume you want to bump power, if so you no doubt have a long piston which needs to be either cut down to 150mm OAL or buy the 15mm piston which in is ~$36CA. Check the airgunforum.ca for info. It is possible your gun also has a weaker spring, but the piston length is more important. Once apart you can see what parts you have. This springs # starts with BT9, the lower strength one starts BT5, which is inked on the spring.
Can I use this to convert a Benjamin B5M22PX to nitro? If so, do I need any other items and what velocities should I expect?
You likely have the same deal as the post above, so no doubt a long piston, and maybe the weaker spring. It's also possible the piston has a hole in it, which I forgot to mention above. So you really need to open it up to see what parts it has, then decide how to deal with it. Once all the power limiting parts are fixed you should break 750fps with 14.3gr pellets, even as high as 800 is possible but rare.
It worsk in a Crosman Fury NP 4.5?
It should be the exact same spring you gun came with. You can check with Crosman using your actual model # to confirm, or take your gun apart and check the # on the spring.
does this fit Benjamin Titan??
Yes, it's the oem spring for most Titans. Some had weaker springs and there may be some with odd setups like Herbert below, but it should fit any Titan and make full power.
I have pressure air one crosman phantom 4.5mm which the piston of gas suitable ram if podesse sent the measures thanked thank you v juliao
Can't understand the question. What model # is the gun?
It works for crosman quest 1000x?
It can but you need to modify the gun a bit. See my post below
Will this fit my crosman fury
It will if yours came with a nitro, if not you can make it fit with a little work. See my email below and I'll send how-to info
I have a Benjamin Hardwood model BT9M22WNP, serial number D09X00033. I purchased the replacement nitro piston (ram) but it did not fit, because the original ram has a reduced tip, meanwhile the replacement part does not. What should I do now? Do you have a ram with reduced tip? What part number is it? Thanks
I've seen pix of those but never in person, not sure why they exist. The new one should work anyway since the new pistons shaft should be pointed and will self center in the smaller hole. Your other option would be to drill the hole bigger or buy a new piston, but I wouldn't bother.
Chevota, would you be able to describe the measurement of the piston? my rifle is the detuned benjamin trail n2 .22, you say it should be cut to 150 mm so I am confused as to how you get your measurement , also what about the square cut out on the piston for the trigger assembly , thanks so much for the info
That's the overall length of a full power piston. If you have a CA version it's likely ~175mm. So you need to cut it down to ~150 and drill a new trigger sear hole. You can probably figure it out by looking at it but I have pix with dimensions if you want; chevota at hotmail
Do you sell a gas spring (Nitro Piston) that will fit in an NP2? The replacement Nitro Piston from Crosman did not preform any better than my original. It's shooting .22 cal. 14.3 Crosman Premiers at aprox. 700 fps. Yes, I have changed all seals and tuned the gun.
Interesting... Could be the barrel is too loose, or has a tight spot, or maybe whatever you're using to measure velocity is not working so well? Is the breach seal actually sealing? Sometimes the barrel stops before it puts enough pressure on the seal. chevota at hotmail if you want to discuss it
will this give my benjaman titan np 22 cal more power
It is the oem replacement spring for a Titan and most other Crosman/Benj nitros, so no. Now if you have an oddball 695fps one or your spring has leaked then this will bring it to full power, assuming the new one hasn't leaked too. You can estimate yours by measuring the cocking effort, if peak effort falls below 28lbs then it leaked or is an oddball low power gun. If your spring is good then I suggest tuning the gun for more power, which varies but ~20% gains are common. See below email if you want info
Can this replace the coil spring in my fury2
I believe the Fury II was only coil spring, if so then this nitro spring can be installed w/o too much effort (imo), but how is too much to post here. Write me at chevota at hotmail for pix and details
Chevota what exactly do you cut on the inner piston to bring it down to 150mm
Probably better to show you pix, email me at chevota at hotmail
Can this be used to upgrade the Crosman TR77? Is a compressor required? Does it come with instructions?
See my re: to the Fury II post. Most people use a compressor, I do not. No instructions.
Can this be used as an upgrade for the Crosman Quest
Yes, see my re: to the Fury II a few above
Will this work on the umarex surge spring piston ?
I'm pretty sure the answer is no. Umarex has two basic designs for their guns, one is a clone of a Diana, the other is a modified version of that clone. The new modified one can likely accept the nitro, the other cannot. The original clone has the safety coming out the back, the new one has the safety in front of the trigger. The Ruger Yukon would be an example the new version.
will this fit in my np trail nitro as a replacment
Basically they have three Trails which each take a different spring; the Trail XL, the Trail NP2, and the others. This one fits the others. To be sure, see my reply to "Art" below on finding your part #.
Is this what is called the NP2 Nitro Piston? Can it replace the older nitro piston in some Benjamin/Crosman guns. Would this be considered an upgrade over the older models if it is the NP2? I have all the tools to replace them if that is the case and will do it. Thank You Anyone :^)
This is not the NP2 version, not that they're all that different. The main difference in the NP2 is the piston, this is a spring. No the NP2 piston will not fit your gun, nor would it be worth the trouble if it did. This is a replacement spring for nitro springs that have leaked, and this model was used in most Crosman and Benjamin guns, but not all of them. Look on the Crosman site under owners manuals for your gun, then the parts list and see if this one's part # BT9M22-00-5 matches.
Will this fit in my benjamin titan gp?
Yes, it is likely the same exact part #.
will this piston fit in crossmans phantom
It depends on which Phantom you have. This fits most, if not there is another that will. It doesn't just drop in to replace a coil spring, it requires other parts and/or modifications to make it work. If you buy all the parts to make it work I think it would be cheaper and easier to just buy a nitro gun. If you have the tools and can improvise then you just need this spring. Then there's the why? If you just gotta have it then get it, but if you want more power and/or a quieter/smoother gun there are much easier and cheaper ways to make your existing gun do that. So yes it is possible one way or another, but for most people this spring is only good for replacing one that has leaked out. Maybe ask in the Canadian Airgun Forum for more details. Specify the model #, caliber, what you end goal is and why.
i have a benjamin trail that shots 495 fps if i install this piston will it increase the velocity of my gun ? and will i need to do other mods to get the 700fps im looking for ?
Jason: There's a "kit" sold by some place in CA but it's simply an oem full power piston and spring. Better imo to find out if your gun needs both parts. If you do need a piston then I'd consider shortening yours since they're expensive. If you only need one part, or all parts, I think The Gravel Agency may be the better choice. Be sure to get a new main seal too!
What is the name of the kit mentioned in the first answer for the bengimin trail np?
thankyou very much chevota bye cutting the inner piston to 150 mm and adding this nitro piston to my gun i now have the power im looking for it actually will shot threw a 1 inch peice of ply wood no problem it a bit scary i havent put a chrony to it id bet im getting 800to 900 fps now thankyou or over 1000
They detune the guns for Canada several different ways, so I would figure out how they did that first, then work on undoing it. They also detune the 177 differently than the 22. If it has a hole in the piston, plug it. If the piston is longer than 150mm, shorten it or buy the 150 version. If it has a nitro now it is probably the lower strength one, but probably a better spring and it will hit 700 in 22, maybe 900 in 177. If you only installed this spring then your gains would probably be minimal if any. If it has a coil spring now then you need more parts and it's more hassle to do nitro.
stephen so you used this piston and it upgraded your gun ??
There is a kit that has a new nitro piston , that is stronger and a shorter piston ,that gives you a longer stroke , I put this in my TR 77 NPS went from 483 fps to 826 fps
Looking for ram for Beeman Sivler Kodiak X2 will this work?
I believe it is possible, but it certainly doesn't drop right in. You'll need to improvise to make it work in your gun. Basically the nitro has to be centered at each end, so look at how Crosman does that and improvise. Much easier and cheaper imo to just tune your existing gun and maybe buy a Vorket spring for it. Properly tuned you won't be able to tell it's not a nitro, except the cocking effort will be less.
Is there any kind of Nitro piston conversion for the Stoeger x20s
The Stoeger X20S is just like a Crosman, example an Optimus, so the same parts and everything to convert it. It's not worth the trouble imo, and can be expensive. Better to just tune the gun as-is imo.
Just bought a new Trail NP2 from Pyramid and it's really a stomper. I'd like to convert my old NP .22 to a .177. Can I do this by installing this gas piston and changing to a .177 Trail NP barrel? Or does it require more? [email protected]
You don't need a new nitro, just the barrel. "NP .22" could be one of many guns so I can't say which barrel you need, but you can look up the parts list for the 177 version of your gun on the Crosman site. If your nitro has leaked out and you need a new one then again you need to know which gun you have so you can order the correct nitro.
You would need to ask www.crosman.com about that one.
Does this piston serves for a benjamin regal .22?
They have at least five different nitro's that I know of, but yes this is the one the Regal uses.
I would check with Crosman. I believe all the benjamin crosmans use the same Nitro piston except the NPXL it has a larger piston.
serves the piston for a benjamin trail xl 1500 ?? refaccion as I get for this model.
No it will NOT fit the XL. The XL uses a nitro unique to the XL, which can be ordered from Crosman but I doubt they ship outside the states. See four posts down for more info.
It will fit your rifle.
Does this piston upgrade from my Canadian 495 fps detuned piston or is it still within regulation
It will no doubt fit a nitro gun, and may make a little more power, but you need to fix the piston first. The piston will have a hole in it and/or be longer than 150mm, fix that and then decide if you want a stronger spring. If your guns has a coil spring then it's more money to convert it to nitro. The fps will vary drastically on the parts, condition of the gun, pellet weight and caliber, so it could anywhere from below 500 to over 1300. And odds are any of the mentioned modifications will push or exceed the legal limits.
You will get exactly 765 fps, after replacing the spring ,with crosman hollow point pellet, and ~ 500 fps with heavy pellet like eunjin 28.5gr. In Canada You will need PAL for this air gun. Cheers
I imagine it will increase your velocities as these are pistons made for unregulated rifles.
I had a hard time understanding the question. Normally this does not significantly increase velocity. This item fits Benjamin Trail and Crosman Nitro Venom air rifles.
What are the dimensions of this, length, diameter, etc? Thanks!
Is 10 " 1/8 long.
OAL is 260mm +-1. OD of the body is 18-18.25mm. Body length is 151mm +-1. Shaft dia is 10mm. Shaft length is ~109 depending on how you measure.
I would suggest calling Crosman
Hello, is this nitro piston fit in Nitro Venom Rifle ?
Yes it is the exact same one.
You would have to contact Crosman and ask but I believe it will
is this the replacement for the Benjamin trail np xl in .22
You would need to contact Crosman directly and ask for part # BT1500-00-2. Same spring for all the XL guns. If taking the gun apart I would suggest this too: http://tinyurl.com/PyramidWaltherSeal Works better than the oem seal, but I suggest you remove the sharp edges inside the receiver tube before inserting it. Looking at the old seal will explain why.
I need the XL you have it ??
No, this is for the standard Trail models, not the XL.
Hello, Could this be installed in my Benjamin .22 classic to replace the spring?
Not sure, would need the actual model #. But an easy way to tell is if the receiver tube is ~30mm then it can be converted to work with this spring, but not worth the $ imo. If the tube is ~33mm then you'd need a different spring, and even more expensive to convert. I'd stick with the coil spring myself, much easier and can be made as smooth and quiet as a nitro.
I do not think it will work.
Hello, I have a canadian reduced 500 FPS Benjamin Trail Nitro Piston .22 cal, i was wondering that if i bought this piston it would bring the gun back up to its original model power/fps of 950 fps, or what do i need to buy/do to upgrade it rather than buying a new rifle.
There is also a version where they put a hole in the piston. I guess you'll have to take it apart first to see which special mod they did to it. At least the hole version is super easy to fix.
Apparently there are two different low powered guns, one uses a lighter pressure gas ram, the limits the stroke. I believe you have the short stroke version so you'd need to buy a regular piston and whatever else makes it different. As for the ram I'm not sure if it has the low pressure unit to not. Look at the parts diagram for a normal Trail here: http://crosman.com/pdf/manuals/Trail%20NP%20EVP.pdf to see the differences. You won't get 950fps from a normal lead pellet btw, they're closer to 700 +- 50.
hi which measure the piston air?
Not sure what you mean. Can you explain your question?
Hello how many ft-lbs has this nitro piston?
They vary from gun to gun depending on several factors, but 16-17 is typical for the guns this fits, meaning the Benjamin Titan, Trail, and similar. You might get as high as 18.5, or low as 13 too. Most can be tuned to make about 18.5 which is basically eliminating the flaws, leakage, and friction.
That depends more on your gun than the nitro spring.
Is this nitro piston fit my crosman vantage 1200 spring piston rifle? Best regards Pietro
It will if you already had a nitro spring. If you have a coil spring now then you'd need some parts and a simple modification to make it fit. I did it with my Vantage
