Works as described, easy to dial in the field - 2A Armament Titanium Regulated Bolt Carrier, Bolt Carrier Group (BCG)s

I stuck this on a 556 that I shoot suppressed. It definitely helps get the gas blow-back out of your face when shooting suppressed. It even blows a fair amount of the gasses to the right side. I even had a shooting partner say "what the!?!" when he got a small gust of gas blow off at him a few feet away to the side.

Took me just a few minutes to dial it into the setting for my particular gun/suppressor combo. Highly recommend trying this if you can stomach the high price instead of ripping out your gas block to install an adjustable one.
