Archived [ARCHIVED THREAD] - O-Ring for USP 45 Tactical AAC End Cap
Posted: 4/5/2014 6:04:14 AM EDT
I purchase an end cap on eBay, was not too happy with it. After searching extensively online I saw the AAC version, much beefier, better quality. I ordered it, even though it said it would come with the o-ring. It didn't. Called and emailed the place I bought it from, they weren't even sure if it was suppose to come with one. Anybody know the part number for what I'm looking for ?

I have found that the barrel o-ring works well in a thread protector.  You should have a couple of spares included with your pistol.

If you find something that works, please let me know, I have one (AAC) on my HK 45T, it has to be the same one. barrel o-ring seems to maybe be too much? I don't have that many..
and you're right it did not come with one.

I just got my AAC thread protector in and mine actually came with the O-ring, not sure why yours wouldn't have. Unless they realized there mistake by the time I ordered mine. I would try calling them again. The o-ring is in between the threads and the front of the cap BTW. Took me a minute to see it, figured it would be in the back.
