having problems with my qb57 air rifle

Recently bought at a yard sale, got some new pellets since ones in case looked crappy, also got oil if I need it. Went and pulled back arm, put in pellet, pulled back a little again, pressed the release at loading point and nadda. Now the arm is stuck in the pulled back position and I'm at a loss at what to do or what I'm able to do.

Here it is now.

So while you have the the release depressed you can't push the arm back?
I'm looking at mine trying to see what could be the problem.

I pulled the arm back in the position it's in to load it, loaded it, pulled back again, pressed release and now nothing moves at all.

Are you keeping the release pressed while you pushing the arm back.

Yes as well as when I'm pushing the arm back into position.

Sorry but there are two "releases" to cock the gun, the first is on the cocking arm to unlock it from the body and the second is the bear trap lever to the left of the loading port. So you have those both covered then? So back near the hinge there is a little bent tab that senses? when the cocking arm is back in place and allows you to pull the trigger, these things are hit and miss and mine didn't work on the first QB I got so anyway if the little tab is forward then it won't let you return the arm so if you can move it towards the but it should allow you to close the arm. It may be binding on the stock or have been bent to stop its natural movement. Give that a try.

Yes I've pressed both the release on the arm lever and the bear. I do see the other you are talking about near the butt end and it appears to be back and I am able to push it forward. If I remove the barrel from there handle grip would that be a bad thing to do. I've not taken anything like this apart yet......😁

You have to be very careful since the rifle is cocked and that arm can slam back pretty hard, enough to break bones if your hand got in the way.
Did you try with the little tab in each position.
When I am handling my rifle with the arm back I hold it in my right hand with my elbow against the arm so if it suddenly released the arm can't slam back and in particular the breech won't slam closed when I'm loading a pellet.
I would find a piece of wood that fits in the breech as a extra safety not too tight so there was room to tell if the arm was working and then take the stock off to have a look at the mechanism at the tab. I would leave the barrel on you may need the leverage. I was able to decock one of my rifles by firmly holding the arm with my right hand, press the beartrap with my left thumb while holing the stock in my left hand and pull the trigger with a spare finger on the left hand. I didn't just hold the pistol grip because I had heard of one breaking. I'll try to get pictures of my rifle in disassembly.

Yes I've gone and tried all that and still nothing. I'm wondering if it's not going back far enough to then be able want to go back in its original position. When I pull back I notice the silver color of the chamber does not quite go all the way back. Does yours? I can feel it go back just a little more when I pull it and I press the bear trap and push forward so a no, even while messing with that little switch under the arm. It's still in one piece so far....lol.[/img]

When I cock my rifle the silver cylinder is not visible in the breech til I push the arm forward. It may be worth trying to de-cock it and in order to do that the little tab needs to be jammed forward then holding the arm firmly and depressing the beartrap lever then pull the trigger slowly letting the arm go forward. It will be under spring tension so have a firm grip on everything. Once that is done I would get some sort of spring compressor and dismantle the rifle to inspect the interior. I cocked then de-cocked my rifle to check the position of the cylinder while just using my hands to get the safety catches in place and only sustained minor injuries Smile

Well I guess its time to break out a spring compressor and tear it down.

The trouble is its cocked, I wouldn't want try to disassemble a cocked springer you would need one heck of a spring compressor.

Yeah, you would need to take the barrel off and put it in a big vice or something similar.

The spring will need to be replaced after being compressed for so long too.
