AA chose 9/16 thread pitch to permit use on thinner profile barrels prior to 5/8x24 becoming pretty much standard with 7.62/308 barrels. I’m not sure why AA hasn’t switched to 5/8x24 other than not wanting to deviate from past practice.
I have a 16” and 18” barrels from the previous group buys and the profile of the group buy barrels really make for a versatile AR-15. I’ll have to admit I like the black Nitride finish with the Monster logo.
