Barrel O-Ring All HK .45 Caliber Pistols – Green

(1 customer review)


A rare find as we have found a small lot of the original HK German green colored HK .45 O-rings. Get them while you can as they are no longer available in green. The green o-rings were first used when HK introduced the use of o-rings on the Mark 23 & USP 45 Tactical HK pistols. All HK o-rings are still made of the same material as the newer black o rings only in the original green color.

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 & increased accuracy. The O-ring is the same for all 45 barrels and will fit all of the following HK pistols:

  • HK USP .45
  • HK USP Compact .45
  • HK45
  • HK45 Compact
  • HK45CT, HK45 Tactical
  • HK Mark 23, SOCOM
  • HK Elite, Expert & Other Custom aftermarket barrels with O-ring grooves

We have the best price in the country on this hard to find and no longer offered item. Shop & compare. One-time special buy so stock up!
