The Luxus Arms HM Defense HMP15FMB556C RaiderMC556 delivers a compact AR-style platform built around HM’s patented Monobloc barrel system. This semi-auto pistol pairs a 9.50" match grade threaded barrel with an integrally machined gas block and an 8.50" free floating Picatinny rail, giving shooters a rigid, accurate front end ready for accessories. Forged aluminum upper and lower receivers, an M16 bolt carrier group, and an enhanced grip come together to provide a dependable, easy-handling firearm in a sleek black finish. Designed as a short, maneuverable 5.56 NATO/.223 Rem option, the RaiderMC556 is well suited for range work, training, and duty, carry, and range use where a compact footprint is preferred. The adjustable Close Quarter stock and smooth controls help accommodate a wide range of shooters, while the included magazine lets you head straight to the range. HM Defense’s focus on innovation and precise machining is evident throughout this pistol, from the Monobloc barrel to the carefully finished receiver set. Key Features:
