BCM A2X A2 Flash Hider 5.56x45mm NATO 1/2x28 Black Phosphate 4150 Steel - M4/M16

The BCM A2X is an extended version of the classic A2 flash hider long issued on M16 and M4 series rifles. Machined from 4150 steel with a rugged black phosphate finish, this muzzle device is purpose-built for 5.56x45mm NATO carbines and rifles fitted with 1/2x28 threads.

The A2X retains the proven slotted birdcage geometry of the military-spec A2 while extending the host barrel. When permanently attached via pin-and-weld per ATF specifications on a 14.5" barrel, it brings the assembly up to the legal 16.1" minimum overall barrel length. The A2X installs directly onto any M4 or M16 barrel with standard 1/2x28 threading, delivering reliable flash suppression for both duty and recreational use.
