Hey everyone, I'm selling my AAC 51T Muzzle Brake.
The thread pitch is 5/8x24 TPI (308, 6.5, 6.8, etc).
Great muzzle brake and I use my other brake (same exact model) with my aac sdn-6.
I just decided to sell this as I'm getting a direct thread suppressor for my 308 bolt gun.
I didn't mount it and has all the shims and Rocksett.
Thanks & Semper Fi
