The HM Defense HM15FMB556 Defender M5 delivers a refined take on the modern AR-15 platform. Built around HM’s MonoBloc 16" 4150 chromoly match-grade barrel with an integral machined gas block, this rifle is designed to provide consistent accuracy and smooth function while keeping weight forward of the receiver to a minimum. A free-float handguard with Picatinny rail and M-Lok compatibility offers ample space for lights, grips, and other accessories without interfering with barrel harmonics. This semi-automatic .223 Rem/5.56 NATO rifle features a 30+1 capacity, Mil-Spec HM collapsible stock, and an enhanced polymer grip for secure, comfortable handling over long range sessions. The rifle ships optic ready, allowing shooters to tailor their sighting system for training, competition, or general range use.
