So ZCI hop up and new barrel upped the fps of my m16 to 356 on 0.2, 312 on 0.25 and 296 on 0.28.... How can i drop it down by 10fps? only thing i can think of is sawing off 1cm of barrel?
yup, the gearbox is all stock. Crazy what a bit of tightboring can do to the fps
with hop tinkering it can go below the fps requirement, but i think i will bring the shorter innerbarrel as a spare to site. just incase it still fires hot with the hop set properly
