Works great

I bought a new threaded barrel that already had one of these. It does a fantastic job of holding the thread protectors on. Gone are the days where I routinely checked to make sure it was tight every couple of magazines.

O-ring to secure thread protector

Worked great. I slipped one on under the thread cover. Took the Texas LTC class and the thread protector was still snug.

Fits well

It seems to hold the thread protector in place. I haven’t shot since the install, but the thread protector seems much more secure than going bare.

O-ring Perfection !!

Damn fine little rubbery rings of perfection ! Each has a hole in the center that fits perfectly over the tip of my threaded 9mm barrel. My comp and thread protector immediately snugged up to these beauties & I'm sure they will no longer try to walk away from the barrel and go AWOL during target practice marathons.

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
