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.Instructions: Keep a very light coating of non-solvent gun oil on the o-ring. Push the guide, brass end first, into and through the center of the barrel extension. At the same time, a slight twist the black delrin will ease the o-ring into the bolt opening. Twist until the guide bottoms out. To remove the guide, reverse the twist while slowly removing the guide.
