Complete with B/C/CH and extras! Excellent condition. I shot around 400 rounds with an occasional malf so I sent it back to Armalite where it got the chamber and ramps polished, headspace checked, McFarland gas ring, and a general tune up of the bolt/carrier. Life time warranty. Black and Green guards included. $625 shipped OR trade towards an AR10T upper.
