Easy install, fully supports bcg - Primary Weapons Systems PWS Enhanced Buffer Tube, Mil-Spec Gen 2 Ratchet Lock Endplate

What I like most about this style of buffer tube is that it supports the BCG all the way through its movement. From battery to hold open, the bolt carrier doesn't move, which reduces some of the failures associated with broken buffer retainers. The bolt will tip down slightly when cycling, which chews away at the little nub on retainers. That can break off, fall into the FCG and prevent the rifle from working. The enhanced buffer tube also reduces wear on both the buffer and the bolt carrier. Good buy for any rifle.
