Right, hello my name is Joel, not new to airsoft, but new to computers,
Anyway I'm putting a Laylax VSR SP150 Spring in my Tokyo Marui VSR-10 G-Spec, When I get it of course. But, I will need to change a few things in order to use that spring. What I would like to know is, what would the FPS be if I put that spring in? Also, I would like to know what I would have to upgrade to use the spring. SOMEONE PLEASE COMMENT BACK!! ~chimaria
