    It protects the threads

    Posted by J on May 17th 2021

    Not much to say, threads fine onto a variety of AR barrels with 1/2 x 28 threads to protect all the threads, and is flush with the end of the barrel. Finish seems sufficient 5 stars because it does what it says it does, but would have been truly perfect for me if it had some front depth to it so that the protector extended past the barrel end, so that the barrel crown isn't fully exposed to drops or knocks (yes, I could achieve this by using a crush washer but the looked wouldn't be as sleek.)

    Love it. My personal I love to see the fireball at the end of my guns when I’m shooting them. I put this on my 556 ar and man at the shooting range I always get people asking me what is it that I’m shooting.
