ArmaLite's M15TAC14 meets the needs of front line users as well as home defense conscious civilians for a platform that is compact and modular from the factory. All Tactical Series rifles include Magpul MBUS flip-up sights and MOE + pistol grips. The dual purpose, flash hiding compensator tames recoil while reducing signature. A sturdy 10 key mod handguard provides ample hand space and a full length MIL-STD 1913 12 o'clock rail for sights and accessories. This rifle has a Magpul STR multi-position collapsible buttstock. This model has a 14.5 double-lapped, chrome-lined, chrome moly vanadium barrel pinned to a 16 carbine-length gas system with an adjustable gas block.
