I dont know who told you that a tight bore causes a decrease in fps but they are full of it. I have a 6.04mm systema in mine and i saw a 15-20 fps increase.

I have heard from some that only ICS Outer Barrels work?
Supposedly Tightbores cause lower FPS?
THere is no aftermarket Metal Bodies for the ICS?


I am selling my rifles to get an ICS M4.

Buy a free float M4 and M16 lenght RAS units both with folding sights, tightbore,
Systema Magnum motor, Crane stock running 9.6v 3000mah, New Handgrip,
Magpull Trigger Guard, and a totally new uppermechbox and upper reciver
shell and 2nd hopup so I have a 2nd upper set I can just easily swap out in a min or so.

Also if you feel like it.. Post your ICS M4/M16 with pics and Specs on what
you have done as per upgrades and accessories.. I would like to turn this
Thread into an ICS Info Section since there is very little on them.
