ArmaLite M153GN13 M-15 | .223 Wylde | 13.5″/16″ Barrel

The ArmaLite M153GN13 M-15 Competition is a purpose-built practical/3-gun rifle chambered for .223 Rem / 5.56 NATO that pairs a lightweight adjustable MBA-1 stock with a precision-oriented trigger and tunable muzzle device. The rifle features a stainless steel barrel listed as 13.5″ that is pinned and welded to its tunable muzzle device to present a a 16″ external profile under some listings; an adjustable gas block and free-floating handguard allow the rifle to be tuned for different loads. A quality low-power variable optic such as the Vortex Viper PST Gen II 1-6×24 (commonly available under $1,000) is a suitable match for the intended use and will maintain the rifle’s fast-target-acquisition capability.

Typical applications for this rifle include competitive 3-gun/practical rifle matches and precision-oriented AR-platform competition or positional target work where a light, tunable package and adjustable stock are advantageous.
