I got these for $5 today:toothless, anybody know anything about them? There Crosman 1008 repeatair 8 shot .177 cal pistols that take C02 cartridges. I've a;ready gotten a laser sight for the silver one. I had to change the black one's receiver and put it on the silver one for the sight cause the original one didn't have the groves in it for the sight. The silver one is my little brothers thats why I did that.
