Fits Agency Threaded G43 Barrel

Its Slimmer than the original o ring from agency, but fits great on an agency g43 threaded barrel. Secures protector nicely

Just what I wanted

I had a great overall experience. Fairly priced. I received my product pretty quickly and it works just how I need it to. Very happy with this company.

Low profile, high quality, and they get the job done. Running these on three Glocks with threaded barrels with comps - everything stays tight. Hundreds of rounds and I haven’t had to tighten up anything. 5 stars all day

A perfect fit on my PPQ Q4 TAC and the thread protector is going nowhere after firing 150 rounds. Good thing I'll also be using these on my P10c.

Hate these. I much prefer to have my thread protector fly off when shooting. Even better when there is big boomy bang shrapnel bomb when a round hits it. Terrible product, takes all the excitement and imminent death out of shooting with a loose thread protector.... All joking aside, they do what they say they will do and they do not melt. They fit well, require a bit of fanagling to get over the threads but I'd rather have that than a loose fit. I use these on two different firearms, they work the same on both. Fast shipping and great people. 10/10.

These rings are great! I bought a rival arms threaded barrel but the thread protector loosens with very little vibration. I purchased these o rings and blacklist thread protector and now the thread protector stays secure. I would definitely buy these again!

I used these after eating heavy Mexican or spicy Indian. I just wish they made them in brown so they would blend in better.

O rings at a great price. I'll buy more when these wear out. Fast shipping. Colorful notifications.
