Like any rubber O-Ring, good for 1- time use, need constant replacement, good part is that it protects the barrel

Love the selction, price, and fast shipping. But wish that you offered a package for the threaded barrels, with barrel, O-ring, and thread protector.

"Original HK O rings"

Anthony Le on 2/19/2012 11:30:12 AMVerified

Overall Product Rating:

These are original HK O rings. They fit perfectly to the HK barrel. Not much else to say about it. You can't go wrong buying this if your need a replacement. Thanks.

Overall Product Rating:

These o-rings are a smart purchase for any USP owner with a threaded barrel for their pistol. These units require replacement over time and HK is the best place to find them.

"Extra Spares"

Overall Product Rating:

Plan to put lots of rounds through my USP so I figured having a few extra O-rings wouldn't hurt.
