Its been a long time since Ive been here...for addition info, I just contacted AA to confirm the thread pitch on my circa 2007 carbine barrel. I was told it was threaded at 3/4 x 28, but there was also an I believe in the response. If anyone has different info, I would appreciate it. If I wanted a brake for this thread, I see Harrels radial brake is an option. Are there others?
