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?
no no, The stock g&p 509mm innerbarrel has the same fps on 0.2 as the 340mm zci inner barrel i have for an m4. the 356fps is from the 509mm zci inner barrel i was wanting to swap the stock one for
