The CMC Triggers .750 Internal Bore Low Profile Gas Block, Black is a gas block for AR-15.
Unique, all-steel gas blocks expand the versatility of your rifle by providing a variety of accessory rail and hand guard mounting options. Especially helpful in customizing short-barreled tactical rifles. Designed Specifically for AR15 s with a barrel .750″ O.D. at gas port.
Low Profile version is a low and narrow, one-piece block designed to fit inside most free-float hand guards; allows use of rifle length forearms on carbine length barrels for a clean, streamlined look and added gripping surface. Securely attaches to the barrel with included dual hex head set-screws.
Works in conjunction with all CMC Triggers AR-15 Nitride Gas Tubes or standard Mil Spec gas tubes and hardware.
The gas block sits on the barrel and feeds gas to the action. Check the barrel journal diameter matches the gas block, and have it fitted by a competent armorer.
