I'm curious as to the speed/peformance with 168's or 175's of the shorter setup. I keep going back and forth from 16.5 to 20" barrel.
20" would obviously have some advantages of keeping the speed up a little better and regulating pressure when suppressed, as well as a closer representation of another upper I'll eventually have built in 6 CM with a 22 or 23" barrel.
Anyone?
