Barrel is great but the threads are not listed correctly. They are not 5/8x32 they are 5/8x36.

Hello! I just checked with our armory team and we looked at these barrels, and we were able to confirm they are 5/8x32 threading. If you have a lemon, these are backed by our lifetime warranty. Please let us know if you would like to work on an exchange or a return, if you have any issues. M.E.
Shoots well but heavy
Excellent value barrel. Well worth the money. Shoots well. It's just so heavy, but lighter barrels are 2.5x more expensive.
USGood heavy barrel but some issues
Barrel mated with my upper just fine, but my muzzle device gave me a lot of trouble, it seized on the 2nd or 3rd thread and took some work to get on. I'm not sure if the barrel or the muzzle device is to blame, but both say they're 5/8 x 32 so I know the threads are correct. I like that the barrel is notched for the gas block pins, and quality is good for the price point.
