Spent a couple of bucks for an old broken break barrel single shot air rifle. The rod that depresses the spring was not attached to anything. Took it apart and reinserted the charging rod. Worked like a champ and seemed to put out some serious air. Problem is it won't charge with the stock mounded. Something is catching somewhere. I noticed some one had ground off part of the rod, I guess to give it some clearance. After breaking it down a few times I managed to bend the cocking rod, putting a stop to anymore fiddling with it. Are parts available for these things. I think it's either a model B2 or 61 or 62.
