Hi. Before I start taking it apart, I figured I'd ask here first. My grandson has a Crossman 795 (break barrel) and every now and then, when he cocks it, there is a sound that something is getting hung up on plastic. In order to get it to cock properly, I have to really crank the barrel, and when I do it almost sounds like the plastic is going to break. After forcing it once, it works fine for a couple hundred rounds, thne it does it again
Any ideas what might be the problem and how to fix would be appreciated.
Thanks
crossman 795 problem
Thanks for the schematic, that helped a lot. I believe I found the problem, the trigger and locking mechanism all seem to be fine ( it has only fired about 800 rounds). During the cocking, I watched a bit closer this time and noticed some movement between the trigger housing and the extension tube so I pulled down a bit harder on the barrel while cocking which caused it to hang up, and the space really moved. (all screws were checked and tight)
I then took the rifle apart and was able to see exactly what was hanging up on what. The back of the piston was actually catching on the front of the trigger housing, causing it to misalign.
The way I fixed the problem was to insert some shim pieces on the outer back of the trigger housing where it buts againast the inside of the stock assembly, and a bit smaller shiming around the lower part of the trigger housing where the screw goes up through the stock behind the trigger guard. This resulted in no movement at all, and the space is closed up completely. I fired a few rounds to check it out and all seems fine now.

It's not a bad rifle, I don't think. The one he's got has the scope lands, so I got him a scope for it too. (It seems not all 795's have the lands). It is very easy to cock, despite the problems mentioned before. The trigger is nice and light and has very little movement before a round is fired which takes a little getting used to. It sounds twangy, and of course quite plasticky when fired. It seems to be reasonably accurate at 10 Meters, with or without the scope, and has a fair bit of kick in comparrison to my Winchester, which is a heavier rifle. I'd say the 795 is a fine rifle for a young person's first, even with all the plastic.
He had a choice of the 795 or a Remington "Air Master" at WalMart and he picked the 795, which seemed to be better made than the Remington at first glance.
My own rifle is a Daisy Winchester 500XS, which is definitely a much better rifle (in my opinion) despite the trigger problems that everyone seems to mention.

I think it was the wood finish of the winchester that caught me cuz I really didn't have a clue in what I was looking for. There was a lot of discussion in the winchester forum about mods to the trigger to make it better, and I do agree it was really hard when I first got mine. The only thing I did with mine was polish the rubbing surfaces of the trigger mechanism and put in some lithium grease. It works fine now. It is quite stiff breaking the barrel mind you, but with it being as stiff as it is, I have to cock it if my grand son wants to shoot it. Is that what they mean by gun control? ha ha.
I'm not too sure of the velocity since i really don't have anything to compare it to other than the crossman, but it does a major number on those plastic army men that you can by down at the dollar store.
I've never really done any velocity checks, and I really don't plan on doing any mods to increase the velocity either. When I pull the trigger, it seems to be instantanious hitting the target at 8 meters.

One thing I didn't expect was the front sight ( muzzle end) being plastic. Interesting enough, mine went and moved on me and I didn't even realize it till I put a hole in the wall behind my pellet trap. I re set it, then put a small mark under the barrel and under the sight so I can quickly determine if it has moved again. I guess I must have bumped it some time or other.
One thing I thought was rather odd, the crossman manual specifically stated not to shoot it without a pellet, and the winchester manual didn't say that at all. I alway dry fire once after cleaning to make the oil goes down the barrel, and to prove the rifle is clear and safe. So far it hasn't bothered either rifle. Any idea why one would go to great legnths to discorage such a thing and the other didn't.

Well they say that it can wreck the piston head by dry firing which is not true. Unless you use your air rifle like a cap gun and shoot consecutive shots which makes the compression tube very hot and will singe the piston seal. But then again you would have to shoot like 100+ consecutive shots to actually wreck anything. But I don't recommend using your air rifle as a cap gun either. 
ONE SHOT, ONE KILL
