Installed this barrel last week. Headspace checked out well. Came with a flash hider that I did not expect which can be used with AAC cans. Barrel is already set up for use of taper pin. Went through 3 pins before I was able to get one through; however, connection is very solid and function is flawless. No issues with bolt locking back.

Advanced Armament Corporation wrote the book on 300 blackout with this barrel. Comes with a 51T muzzle device. Get one - does not disappoint! I am loading mine into a Radian Weapons upper receiver with handguard in the 8.25 length. Got both from Optics Planet.

My barrel also came with a 51 tooth flash hider (looks like the $90 one sold individually on optics planet) which is real cool. Overall, i am very pleased with fit and finish. Have not shot yet, but looks great on my honey badger clone.
