Heckler and Koch .45 ACP Caliber Barrel O-Ring in Black
A great spare and a much-needed part for your HK barrel. This factory part is a high-wear item, as the O-ring provides the seal between the slide and the barrel, which provides a secure lockup with increased accuracy.
The O-ring is the same for all 45 barrels and is compatible with all of the following HK pistols:
HK USP, USP Compact, USP Tactical, USPC Tactical
HK45, Compact, Tactical, Compact Tactical
HK Mark 23, SOCOM
HK Elite, Match
Other .45 ACP barrels that use an O-ring

Hk part, of course available at hkparts. Shopping was easy and shipping was fast. This is normal wear part, but the accuracy gain is worth the 5 buck twice a year, although thats still an expensive o-ring. Also useful to place one at the base of the barrel threads, helping the thread protector stay on with tension without having to wrench it down so tight.
