Ar-15/M16/ 308 Ar Cleaning Rod Guide - Rod Guide, Ar-300 Aac Blackout, The combination of limited chamber space and the large tube inside diameter needed for brush clearance eliminates the possibility of any type of chamber sealing o-ring. We have incorporated a front brass bushing, which centers the guide in the barrel extension and butts up against the chamber opening. The large o-ring on the back end locks into the bolt opening at the rear of the receiver to reduce longitudinal movement of the guide during the cleaning process.
