Aero precision adjustable gas block - ar15.com
Shipped real quick and had the new adjusting screw in the box. The R&R was easy and best to do with the block on the barrel. I haven't had a chance to get out and try it yet. Have a 16 308 with carbine length gas I'd like to know where they are $52 as was posted a few posts up. I need another one for a 12.5 308 with a carbine gas system.
