Hi all, about 20 years ago I bought one of these and stuck it my dresser drawer and its been there ever since. Last weekend I decided to take it out and put a few rounds through it. It shot alright at first but started jamming up fairly regular. Does anyone have any info on these guns, I didnt pay much for it so I'm guessing it a cheap gun to being with. If it didnt jam up so much I'd be happy with it..
