Current Gas Port Specs?
Posted: Sat Oct 12, 2013 8:12 pm
I'm thinking of buying a 1x7 twist CMMG 16" barrel and I'm wondering which gas system to get. My old barrel is a 1x8 carbine length that has run well with most ammo. I don't remember what the gas port is but I seem to recall it is pretty big.
Anyway I wanted to check and see if they've made any changes other than the twist rate.
