Hey guys, just looking for some input from other like minded individuals on my rifle build. I do have a complete rifle as of now, it started as a CMMG M4LE (16" barrel, carbine length gas system). I've made minor changes to rifle, such as a low profile gas block to accommodate a longer rail, new stock, mostly cosmetic. I'm looking to do some interior work, mainly to reduce felt recoil (buffer, spring, possibly a bcg, muzzlebrake). Looking for some input from experienced builders, shooters, and operators; any input is appreciated.
