HK45, USP, Mark 23 Barrel O-Ring - .45 ACP - Red

HKP HK .45 Barrel O-Ring All Caliber Pistols - Red A rare find as we have found a small lot of HK red-colored HK .45 O-rings. All HK O-rings are still made of the same material as the newer black O- rings only in the HK red color. A great spare and a much-needed part for your HK barrel. This part is a high wear item as the O-ring provides the seal between the slide and the barrel, which provides a secure lockup & increased accuracy. The O-ring is the same for all 45 barrels.
