it still has a C clamp, but now it has a rifle stock, a presta valve instead of a schrader, and a good old spring instead of a piece of rubber, now its remarkably accurate, definitely the most accurate projectile weapon iv'e ever made. i now use only tiny steel slugs. and very rarely i'll use a mini nail dart. all and all i'm very happy with it other than the presta, my shock pump can't come of of it without letting all the air out, which is very bad. so i just have to shoot it with the pump dangling off of it.
