ArmaLite M153GN13CO M-15 Competition .223 Wylde 16-inch

The ArmaLite M153GN13CO is a competition-oriented AR-style carbine chambered in .223 Wylde. It pairs a free-floating match-grade stainless steel barrel with an ArmaLite tunable muzzle brake and an adjustable gas block for user-specific tuning. The carbine configuration uses a 13.5″ barrel pinned and welded to the muzzle brake to yield an overall 16-inch barrel and runs on a carbine-length gas system beneath a 12″ free-float 3-gun handguard. The rifle ships optics-ready and includes an adjustable Luth-AR MBA-1 stock and a Timney single-stage trigger for consistent operation.
