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

SKU: HKP-01984

HK German .45 Cal Barrel O-ring For ALL 45 Caliber Barrels

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!

Have been looking for these everywhere! The green O-rings are pretty hard to find these days and it is nice to find a source for them. Fast shipping and the best price I could find on them in both green and black.

"Excellent company"

I was surprised at how fast this company shipped my order. You usually have to wait weeks with other companies. Also you can't beat the quality of HK replacement parts.

"Green O-Rings"

I bought 3 of these for my new HK USP CT .45 and they fit perfectly. Mine came with the factory black O-rings, and this added a unique look to the barrel. Although a very simple product, I was pleased with it.

I ordered some barrel O-rings and the order was processed and shipped promptly. I won't hesitate to order other parts, etc.

"Best bet seal"

Donald Adams Jr on 4/25/2013 3:57:27 PMVerified

Overall Product Rating:

Best bet to make a great seal. I prefer these over the black 0-rings personally.
