HM Defense RaiderMC Features The HM Defense RaiderMC is built around a match-grade Monobloc barrel with an integrally machined gas block a design that eliminates a separate gas block interface and improves consistency shot to shot. The chrome moly steel barrel is threaded 1/2x28 to accept muzzle devices or a suppressor and its Black Cerakote finish provides excellent resistance to wear and corrosion during hard use. A 1:8 twist rate stabilizes a wide range of 5.56 bullet weights giving shooters flexibility in ammunition choice for different applications. Forged aluminum upper and lower receivers with a black hardcoat anodized finish provide the strength and durability expected from a serious AR-pattern build. The M16 bolt carrier group including charging handle and buffer tube assembly is built to established mil-spec tolerances for reliable cycling under demanding use. A free-floating Picatinny top rail spans the receiver for optics mounting while the M-LOK handguard gives shooters ample real estate for lights foregrips and other accessories. The custom trigger guard and Monobloc ejection port cover add refinement beyond a standard AR build and the pistol ships complete with a magazine ready to run. At just over 5 lbs the RaiderMC stays maneuverable for close-quarters and home-defense applications where a full-length rifle isn t ideal. For shooters who want a compact match-grade AR pistol with premium fit and finish the RaiderMC delivers genuine value.
