But the Well VSR10 is pure crap. Everything needs to be changed, including the receiver. You are much better off starting with a good base such a Tokyo Marui and upgrading only what needs to be upgraded (cylinder, piston, inner barrel, hop up rubber, trigger block). It will cost you approximately the same thing as changing everything in a Well, but the Marui will be much more accurate for the same price.
