  • kaelan from Canada asked:

    Will this piston fit my crosman vantage .177. I want to increase it from 495 fps

    • wayne from Canada asked:

      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. Sku 28478 14887 What parts do I need for the upgrade and I live in Canada and I have a firearms license so going bore 495fps is not a legal concern for me. Thanks WayneR

      • Andrew from Canada from USA asked:

        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.

        • David from Canada asked:

          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!

          • Chevota from USA:

            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.

        • andres from Peru asked:

          good morning, this piston is for the benjamin trail np xl?

          • Chevota from USA:

            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.

          • Chevota from USA:

            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.

        • Dave from Canada asked:

          Which nitro piston will fit my crosman phantom.22 Springer and do you ship to Canada

          • Chevota from USA:

            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.

        • Charles from USA asked:

          Will this fit the Benjamin Summit NPT air rifle ?

          • Chevota from USA:

            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....

        • Jamie from USA asked:

          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

          • Chevota from USA:

            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.

        • Luis from Canada asked:

          Hello. I would like to know if it fits on a MTR77 (1200 fps)??? I need it. please and thank you!

          • Chevota from USA:

            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.

        • alex from USA asked:

          Hello Mr Chevota, is this part (CR Nitro Piston) suitable for my Remington nitro piston .177 ? ( item number REM-RNP77) Tks for your time !

          • Chevota from USA:

            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

        • kyle from Canada asked:

          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

          • Chevota from USA:

            That velocity is good so you did it right :)

        • kyle from Canada asked:

          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 from USA:

            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.

        • Gary from Canada asked:

          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 from USA:

            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.

        • RAY from United Kingdom asked:

          Hi,will this fit my Edgar Brothers model 60?

          • Chevota from USA:

            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.

        • alain from France asked:

          bonjour,pouvez vous me donner la longueur du piston ouvert.merci beaucoup.

          • Chevota from USA:

            ~260mm oal. Body ~150mm x 18.12mm. Shaft ~111 x 10mm.

        • Ivan from Croatia asked:

          Hello, does this fit Benjamin super streak .22? Not sure but i think that model number is B1122BTM Regards, Ivan

          • Chevota from USA:

            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.

        • Chris from USA asked:

          Is this the correct replacement for my Benjamin Titan NP model # BW8M22NP?

          • Chevota from USA:

            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.

        • Frank from Canada asked:

          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!

          • Chevota from USA:

            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 ;)

        • Philip from Canada asked:

          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?

          • Chevota from USA:

            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.

        • ivan from Canada asked:

          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!

          • Jason from Canada asked:

            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

            • Chevota from USA:

              See what I wrote to Frank a few above

          • Kevin from USA asked:

            Which one is for piston for np xl. Where can I order it

            • Chevota from USA:

              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.

          • Rod from USA asked:

            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.

            • Chevota from USA:

              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.

          • Oleksiy from Canada asked:

            Can I use this to mod crosman tr77 nps

            • Chevota from USA:

              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.

          • Jan from Canada asked:

            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?

            • Chevota from USA:

              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.

          • Yerami from USA asked:

            It worsk in a Crosman Fury NP 4.5?

            • Chevota from USA:

              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.

          • David from USA asked:

            does this fit Benjamin Titan??

            • Chevota from USA:

              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.

            • Jose from USA:

              Yes

          • Virgilio from Portugal asked:

            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

            • Chevota from USA:

              Can't understand the question. What model # is the gun?

          • Oscar from USA asked:

            It works for crosman quest 1000x?

            • Chevota from USA:

              It can but you need to modify the gun a bit. See my post below

          • Jaguar from USA asked:

            Will this fit my crosman fury

            • Chevota from USA:

              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

          • Herbert from USA asked:

            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

            • Chevota from USA:

              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.

          • qvo from USA asked:

            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

            • Chevota from USA:

              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

          • Rod from USA asked:

            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.

            • Chevota from USA:

              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

          • edmund from USA asked:

            will this give my benjaman titan np 22 cal more power

            • Chevota from USA:

              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

          • bobby from USA asked:

            Can this replace the coil spring in my fury2

            • Chevota from USA:

              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

          • curtis from Canada asked:

            Chevota what exactly do you cut on the inner piston to bring it down to 150mm

            • Chevota from USA:

              Probably better to show you pix, email me at chevota at hotmail

          • David from USA asked:

            Can this be used to upgrade the Crosman TR77? Is a compressor required? Does it come with instructions?

            • Chevota from USA:

              See my re: to the Fury II post. Most people use a compressor, I do not. No instructions.

          • Gio from Philippines asked:

            Can this be used as an upgrade for the Crosman Quest

            • Chevota from USA:

              Yes, see my re: to the Fury II a few above

          • Robert from USA asked:

            Will this work on the umarex surge spring piston ?

            • Chevota from USA:

              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.

          • gordon from United Kingdom asked:

            will this fit in my np trail nitro as a replacment

            • Chevota from USA:

              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 #.

          • Art from USA asked:

            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 :^)

            • Chevota from USA:

              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.

          • curtis from USA asked:

            Will this fit in my benjamin titan gp?

            • Chevota from USA:

              Yes, it is likely the same exact part #.

          • kurtis from Canada asked:

            will this piston fit in crossmans phantom

            • Chevota from USA:

              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.

          • kurtis from Canada asked:

            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 from Canada:

              What is the name of the kit mentioned in the first answer for the bengimin trail np?

            • kurtis from Canada:

              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

            • Chevota from USA:

              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.

            • kurtis from Canada:

              stephen so you used this piston and it upgraded your gun ??

            • steven from Canada:

              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?

            • Chevota from USA:

              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.

          • Joseph from USA asked:

            Is there any kind of Nitro piston conversion for the Stoeger x20s

            • Chevota from USA:

              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.

          • Choctaw1 from USA asked:

            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? choctawldr@hotmail.com

            • Chevota from USA:

              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.

            • Dan the Man from USA:

              You would need to ask www.crosman.com about that one.

          • Maria Olga from Chile asked:

            Does this piston serves for a benjamin regal .22?

            • Chevota from USA:

              They have at least five different nitro's that I know of, but yes this is the one the Regal uses.

            • Greg (PA SALES) from USA:

              I would check with Crosman. I believe all the benjamin crosmans use the same Nitro piston except the NPXL it has a larger piston.

          • Diogenes from Panama asked:

            serves the piston for a benjamin trail xl 1500 ?? refaccion as I get for this model.

            • Chevota from USA:

              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.

            • Richelle from USA:

              It will fit your rifle.

          • Jordan from Canada asked:

            Does this piston upgrade from my Canadian 495 fps detuned piston or is it still within regulation

            • Chevota from USA:

              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.

            • Dariusz from Canada:

              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

            • Luis from USA:

              I imagine it will increase your velocities as these are pistons made for unregulated rifles.

            • Richelle from USA:

              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.

          • AirGunWarrior from USA asked:

            What are the dimensions of this, length, diameter, etc? Thanks!

            • Jose from USA:

              Is 10 " 1/8 long.

            • Chevota from USA:

              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.

            • Jerry from USA:

              I would suggest calling Crosman

          • Bence from Hungary asked:

            Hello, is this nitro piston fit in Nitro Venom Rifle ?

            • Chevota from USA:

              Yes it is the exact same one.

            • Tyler from USA:

              You would have to contact Crosman and ask but I believe it will

          • Joseph from USA asked:

            is this the replacement for the Benjamin trail np xl in .22

            • Chevota from USA:

              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.

            • Diogenes from Panama:

              I need the XL you have it ??

            • Tyler from USA:

              No, this is for the standard Trail models, not the XL.

          • Ian from Canada asked:

            Hello, Could this be installed in my Benjamin .22 classic to replace the spring?

            • Chevota from USA:

              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.

            • Tyler from USA:

              I do not think it will work.

          • Christopher from Canada asked:

            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.

            • Chevota from USA:

              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.

            • Chevota from USA:

              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.

          • Joao from Brazil asked:

            hi which measure the piston air?

            • Tyler from USA:

              Not sure what you mean. Can you explain your question?

          • Francesco from Italy asked:

            Hello how many ft-lbs has this nitro piston?

            • Chevota from USA:

              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.

            • Todd from USA:

              That depends more on your gun than the nitro spring.

          • Pietro from Cape Verde asked:

            Is this nitro piston fit my crosman vantage 1200 spring piston rifle? Best regards Pietro

            • Todd from USA:

              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
