Tech Questions / 400 FPS with M100 Spring????
« on: July 11, 2017, 09:37:52 PM »
My goal is to shoot 350 FPS for CQB so I installed a used M100 Spring in my gun and now it is shooting 400 FPS??? Is it because I have good air seal because even with a good air seal that seems almost impossible. What are the chances it was miss-marked by the company (SHS). Yes I broke in the spring. Its frustrating to me because if I want any lower spring I may have to get a swiss cheese light weight piston.
