Upgrade your Armalite M15 with the UM15TAC16 upper assembly. It comes standard with a dual purpose flash-hider/commentator which greatly mitigates felt recoil as well as flash signature. The 15 inch handguard features multiple MLOK attachment points for the installation of tactical lights, lasers, fore-grips and other accessories, and a full length MIL-STD 1913 picatinny rail allows an optic of choice to be mounted.
