Great barrel bad description
I ordered this barrel and a flash forwarder from another company to the specs listed online (5/8x24) and when it came in was the wrong threads. It delayed my build and cost me money having to send back the incorrect muzzle device. Weird thread pitch. (1/2x36). Other than that and it doesn't have a barrel alignment lug...its a quality product and worked flawlessly in my 9mm AR15 build.
