Beeman PCP chief air leak. I found the leak around the pressure gauge. I replace the o ring and it still leaks. I put teflon tape on the treads and it still leaked. I tried gas line tape tape and it work better but still leaked around the treads. I can pump the gun up to 1600 psi and no more. It leaks around 100 psi in 2 or 3 days. I was thinking I might try 2 o rings seals or some pipe dope maybe anti seal. Any other thing to try?
does anyone know if they have come up with a multi shot conversion so u can add a magazine to this one like they did with qb78 models. also U CAN ADJ. THE SHOT PRESSURE SOME SO U CAN INCREASE THE AIR RELEASE OR DECREASE IT SOME AS U WANT BUT BE CAREFUL , also know that they have come up with a better bolt so that it is not so loose fitting, u also need to bouble up on the bolt sealing o-ring and ck to see if there are any burs in the breach where the o rings seal
I found two sites for good magazines for this rifle
When I shoot my qb chief, it makes this weird that sounds like a machine gun. The sound lasts from half a second to a couple seconds, and when this happens it wastes a ton of air. I don't know if it's the cold weather or the O-ring has bursted. Please help cause I'm thinking of returning it in for a Benjamin maximus
It's called hammer bounce. The hammer is repeatedly knocking the valve open before coming to rest. Typically it's caused by either too much hammer strike (too much hammer spring preload) or by continuing to shoot the rifle well below it's optimal operating pressure. The newer Chief rifles have an adjustable hammer spring...try backing it off.
What type of o-rings does the Beeman qb chief take?
What type of o rings does the rifle take? I can't seem to find anything on this subject.
Does the qb chief hold co2?
It is not recommended for use with CO2
can you get the .22 barrel and replace the .177? it is easy to do. i know i have had to replace the O rings already on my .177 right after i got it, the O rings were chewed up from the factory installation.
is it ok to leave some pressure in the rifle? and how much?
Yes. I would recommend leaving between 1000 and 1500 psi in the gun when storing.
Is there potential for a .25 version in the future? I'd like a pcp option for the caliber that's at the entry level price.
Haven't heard anything about a .25 at this point, but you never know.
Is the barrel the same as the discovery? As in width
The Chief has a 14mm barrel (0.55"). A Discovery barrel is 7/16" (0.44").
is there any regulators made for this pcp yet or know of any compatible regulators made for it to get better shot constitancy and possibly more shots and possible repeater mods or somethign that may fit it to have the ability to use a mag to make it less hassle to reload
Not that I have seen, but you might want to check with Robert Lane in the UK.
Where can I find instructions with diagrams for takedown, cleaning, trigger adjustment or exploded parts diagram?
Can someone tell me which set of see thru rings that can be used on this gun and still see the iron sights ?
how long is the barrel?
This is a QB79 on HPA. How are they getting even close to over 800 fps. I have two of the QB79s and love them but 600 fps is the average velocity. Archer Airguns did the test on mine with HPA and 578 fps is what they got .
It is unregulated and likely has some changes made on the internals. Most of the QB actions that run on HPA are run on regulated bottles, which are usually set to CO2 pressures of 800-1100 psi. That is why they do not achieve the velocities that the Chief is capable of.
Can the same power adjuster be installed on the Chief, that the Discovery uses?Size and bolt pattern the same for end cap?
what is the trigger made of plastic or metal ?
What is the foot pounds of energy on the 177 caliber and a 22 caliber I can't seem to find it anywhere
The .177 should be around 18-20 FPE and the .22 should be in the Mid to high 20s with a heavier pellet
If I did not already have a highly modified Disco, I would buy this gun! If it has acceptable accuracy, this is a STEAL! Get em before they raise the price, and THEY WILL! Simply a LOT of gun for the money! Once they realize they can charge $20 - $30 more and still sell the hell out of them, they probably will!
Can I fill this gun with a air compressor?
If you have a high pressure compressor capable of 2000 psi output, yes. If you mean your shop compressor though, not likely.
I prefer peep sights on rifles that have a front sight. Can the stock rear sight be removed and, if so, is there a peep sight that can mount to the rifle?
!. Does it have the same barrel as the Discovery does,Can someone mic the o.d.?? 2. Can a Gen 2 M-rod trigger go on this gun,like I have on my Discovery?
What is the diameter of the Discovery barrel?
What is the diameter of the Discovery barrel?
It does not. The chief has a 14mm barrel
Anyone know the factory warranty period on this from Beeman?
is aluminum made the reservoir or is steel?
Any idea if the stock from the AR2078a would fit this rifle? I really like the Competition-style (Biathlon) stock.
No, the air tube is a different diameter
I don't know, but it looks suspiciously like an AR 20XX clone! I guess that question needs to go to the manufacturer, or just order the Biathlon stock from some one with a good return policy and try it?
Does it have a built in pressure guage?
All of the HPA tanks shown in the PCP Hookup aren't usable without a 2k PSI regulator valve. I'm surprised this hasn't come up sooner with the Benjamin 2k fills. Is there going to be such a regulator available any time soon?
You don't need a regulated output on your tank to fill a PCP to 2000 psi. Any of the larger tanks, you basically throttle the valve as you fill so you don't overfill. You may want to check out this video https://www.youtube.com/watch?v=8YQrKYbEjsU as it demonstrates it a bit.
Can some1 please do a vid review, I cant find a single 1
Look up airgunweb on YouTube and you'll find a few reviews
Rick has two on YouTube airgunweb look them up
What is the threading of the fill cap?
The fill cap is not threaded. It snaps on and off and is secured via an oring on the gun
I have a basic Daystate type thread-on filler for my scuba tank. will that work?
Not sure what you mean by that. Would have to see a picture.
What county is it made in?
Is the receiver plastic or metal?
Samples seen at SHOT were metal
can i use a benjamin hand pump to fill this gun?
I know Beeman asked (originally) for the gun to not be taken apart. Has anyone gotten into one yet? How similar are the internals to the qb/ar series?
The specs indicate 850 FPS in .22. What weight pellet was used to get this result?
Jsb 15.89 grain generates 831 per second
Aha! In case anyone else needs to know this one, the QB Chief develops 850 fps using a standard weight 14.3 Gr lead pellet.
It does not indicate the weight, but it was most likely the lightest pellet they could find!
It looks like a clone of a benjamin maximus and discovery!
Also an adjustable trigger which the Disco does NOT have! I had to do the three screw mod on my Disco to get a nicely adjustable trigger! Also replaced the breech with a multi-shot breech and put a beautiful fancy stock on the gun, bringing the cost to around $600 - $800 total and making the gun WAY different than a stock Disco!
For sure not a clone of the Disco, and doubt the Maximus also. I agree it looks a lot like the Qb78D or the QB 20XX gun. It is about $100 cheaper than a Discovery, and should be in the same class as that gun, which would kinda make the Discovery superfluous? Basically same gun, nicer stock than Disco, and $100 cheaper! Could be they will have to reduce the price of the Disco drastically?
A heck of a lot cheaper, and the trigger might be a little better. The stock is a little better, with the cheek swell.
It looks like a PCP version of the Beeman QB78D, an excellent CO2 rifle. Other than being a bolt action PCP, of which there are many, I don't necessarily see it as a clone of the Disco or Maximus.
What is the bbl length, is this a choked bbl? Tia, Don
The barrel length is 21.5" and is not choked
What is the psi fill on this gun?
Is this a new model, or is it a "tweeked" version of another air rifle, like the Benjamin Wildfire that is based on the Crosman 1077 (which BTW, the Wildfire is a "hoot to shoot" - and a true 80 shots per fill)?
It's a new model
This Beeman air rifle, where is manufactured ?
China by Shanghai airguns
This Beeman is manufactured in China
How accurate is this rifle?
Mine, pictured under customer guns, hits pill bottles at 50 yards. Distance was indicated by the Parralax on my UTG 4-16x50 scope. Not a great way to measure distance, but I think it's pretty close. Used it on several squirrels at 40-45 yards. Shoots 16g Polymags exceptionally well. JSB18.13g are also winners, but I prefer the Polymags.
I don't consider 10 yards to be a benchmark for accuracy. Needs to be tested at 25 and 50 yards for accuracy. My disco can keep most pellets under 1 inch 5 shots at 50 yards. Any thing less I would consider to be unacceptable!
We're still waiting to get our hands on one, but early reports state that this rifle can achieve excellent to very good groups at 10 yards.
Is the stock ambidextrous?
What kind of pump is needed?
A standard high pressure hand pump like this one will fill the Chief: Benjamin Hand Pump, Fits Crosman...
Any of the purpose built high pressure pumps, available through Pyramyd or another, inferior provider (sorry, but I couldn't resist). I use a hill pump, on accounta I really like pumps named "Hill" and they make a sturdy, long lasting pump. I really like the idea of filling to only 2000 psi in the field, 2k psi is so easy and fast to fill, and a pump won't run low on air on an extended camping/hunting trip.
A standard handpump like this one will fill the Chief. Benjamin Hand Pump, Fits Crosman...
I'm new to "PCP" fired air rifles. How is it filled? have no idea of the process or tools needed. KenA Severna Park, MD
Unless you want to build muscles and spend a lot of time pumping your gun, I recommend you get a 88 cu ft carbon fiber 4500 psi tank and fill it from that!
All pre charged pneumatic air rifles are filled with a special purpose high pressure pump, such as the hill pump, or, a scuba or carbon fiber tank. PCPs typically use either a standard Foster fitting or something called a BSPP probe to hook the rifle to the pump or tank. Pyramyd provides a description of, and application of, which type of fill connector is needed for each specific gun, when you look up pumps or tanks from the web page the gun occupies. You can also call, or use the chat pop-up to ask any question you want, to get an answer in real time. Whatever you need, the folks at Pyramyd will take care of you.
Welcome to PCP Airgunning! Rifles with cylinders of this size are commonly filled with handpumps which operate like a bicycle pump. Here is a video to show you.
Why does this rifle advertise 2 stage adjustable yet in the Specs sheet says single stage
Oops! Small typo. This airgun has a 2-stage adjustable trigger.
What is the air storage tank size?
I had the same question and according to Peter Rodriguez who works for Beaman it is 136 cc tank
Still waiting on hard specs for cylinder. We're approximating 135cc
