Story: I just upgraded my AEG airsoft guns hop-up and barrel. My gun started shooting 400 FPS with my stock spring. I put a m100 spring and it still shoots 400 FPS. My goal is to get it to shoot around 350 for CQB. Before I upgraded from cheap parts it shot about 330 FPS.
Guns new specs:
Completely stock G&P gearbox (except m100 SHS spring)
430mm TBB 6.01mm
ProWin CNC hop-up - http://www.evike.com/products/40058/
Prometheus Air Seal Chamber Bucking - http://www.evike.com/products/31081/
I understand that with the hop-up and air seal bucking and the 6.01 mm barrel make a huge difference in FPS but however I put my OLD hop-up and barrel in my gun and it still shoots 400 fps and my head is spinning and I can't find any to make it not shoot 400 fps. Anyone have any idea how to lower my FPS. Thank you in advance.
