  1. So no lubricant, anti-seize etc, or thread locker?
    I bought a used Ruger Ar 5.56 and the previous owner installed a goofy muzzle brake (looks like the one from a Barret) and I want to replace it with a standard deal

  2. I know you know way more than I do about firearms but I was wondering do you not have to go back and forth a little at a time with a crush washer? I’ve seen a bunch of guys saying you do and others saying you don’t. I didn’t install my flash hider with a torque wrench and just turned it on like you did. I want to make sure I’m not constricting my barrel by over torquing. Thanks
