    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.

    They’re just O-rings for your threaded barrel, not much to say. But it was shipped fast and the humor in the emails were top-notch. Thanks guys!
