The Luxus Arms HM Defense HMP15FMB556 RaiderM556 delivers a compact AR-style platform built around a 12.50" match grade threaded Monobloc barrel with an integrally machined gas block. A 10.38" free floating Picatinny rail, forged aluminum receivers, and a black Cerakote barrel combine to provide a rigid, accurate pistol that stays controllable with its effective muzzle device and ergonomic polymer grip. This semi-auto AR pistol is chambered in .223 Rem/5.56 NATO and feeds from a 30+1 round magazine, making it well suited for range work, training, and duty, carry, and range use where a shorter overall length is preferred. The adjustable Close Quarter stock, M16 bolt carrier group, and thoughtful touches like the custom trigger guard and QD end plate reflect HM Defense’s focus on practical innovation and dependable performance.
