Most Helpful Positive Review Great bang for your buck
Presma Thread Protectors are well knurled in a small tight pattern. Finger friendly. Threaded to specs and very well finished. I got both in black and stainless. These look much better than the pictures. Clean cuts show a quality job. They weight 4oz. Not enough to get your barrel harmonics out of whack.

wrong thread pitch

by c19brown, Verified Owner from ID, United States Written on May 22, 2026
Drop down selection doesn't give you a thread pitch. I selected the ar-15 thread pitch and it turned out to be 1/2x32 instead of 1/2x28

Presma Barrel Thread Protector

by Riskydabs, Verified Owner from CA, United States Written on March 11, 2025
This was a solid buy im not too shabby with removing firearm accessories so when I got this removing the flash hider was easy and putting this on I suggest some PFTE Yellow Thread Tape High pressure tape your threads and put the thread protector on hand tight use a microfiber towel and a wrench and give it a good snug turn don’t over tighten and youll be good to go Great buy for the price
Pros:
  • Everything
Cons:
  • None especially at price point
Best Used for:
  • AR15

I may have got the wrong size

by Beef Brisket, Verified Owner from NC, United States Written on June 5, 2024
It fit for the first couple threads, wouldn’t go the rest of the way, not sure if I got the wrong size but seems like it shouldn’t go on halfway and then stop. *shrug*

Did not fit on my new AR barrel

by Garrett, Verified Owner from GA, United States Written on May 13, 2024
Unfortunately this thread protector will only screw on maybe 2 or 3 turns before completely stopping on my AR barrel. Did not see any burs on the threads but it does not work as a thread protector on my barrel. Giving two stars because it was cheap and the machining seems pretty good besides not fitting on my rifle.
