O-ring For HK .40 cal Barrel - Green

SKU: HKP-01985

New HK German .40 Cal Barrel O-ring for all .40 caliber HK barrels

A rare find and we have found a small lot of the original green colored HK .40 O-rings. Get them while you can as they are no longer made in green and are only offered while supplies last. The green o-rings were first used on the older HK pistols. Still made from the same material as the newer black o rings only in green.

A much needed spare and a much needed part for your HK barrel. This factory part is a high wear item as the oring provides the seal between the slide and the barrel, which provides a secure lockup & increased accuracy. The O-ring is the same for all 40 barrels and will fit all of the following HK pisols with the o-ring groove:

  • HK USP .40 tactical barrel
  • HK Elite, Expert other custom aftermarket .40 tactical style barrels

We have the best price in the country on this item. Shop & Compare no one can ofer them at our price. One-time special buy so stock up while they are priced over 50% off. Order 10 or more and save an additional 20% off!

"It is exaclt what it professes to be"

Overall Product Rating:

It is an over priced rubber o-ring that is fit specifically for the threaded barrel of an HK USP 40. As such it works as advertised.

Buy several. It seems like the tolerances are very close, so don't settle for knock offs.

Overall Product Rating:

I just got a threaded barrel for my USP40 full size. See my review on it. So this is the first time dealing with a barrel o-ring. When slowly releasing the slide, I can feel when it engages the slide. It feels very positive.
