Selling an AAC 51t muzzle brake threaded 5/8x24, .30 cal bore. The brake has a port with two edges that were "bloomed" out when removing the muzzle device. I didn't have a thin enough open end wrench to be able to use the flats so I had to go through the ports with a rod and wrench it off like a troll. The deformation is not that bad, but noticeable.
