Timney single-stage trigger
Forged flat-top with MIL-STD 1913 rail
ArmaLite tunable brake
The M153GN's are Armalite's flagship competition rifles that are built to win. This carbine is compact, light, and ultra-fast. The low profile handguard covers a free-floating 13-in. barrel with Armalite's own tunable muzzle brake pinned and welded to create a 16-in. barrel. An adjustable gas block also allows the rifle to be individually set for optimal performance.
