HM Defense StealthMS5 Features The HM Defense StealthMS5 centers on a 16.25 barrel with an integrally machined suppressor built from chrome moly steel with a 1:7 twist rate that stabilizes a wide range of 5.56 NATO loads. Because the suppressor is machined directly into the monobloc gas block rather than pinned or welded on the rifle keeps its sound reduction without the added length or attachment points of a traditional can. The carbine length gas system cycles the Mil-Spec upper smoothly and M4 feed ramps help feed reliably from the 30 round magazine that ships with the rifle. A Picatinny rail runs the length of the aluminum receiver giving the shooter a consistent mounting surface for optics and accessories without relying on a separate add-on rail. The Black Hardcoat Anodized aluminum receiver and lower feature anti-walk trigger pins a durable combination that stands up to repeated use and field conditions. An M-LOK handguard wraps the barrel for a slim modular grip that accepts lights foregrips and other accessories wherever the shooter needs them. The HM CQB adjustable stock is QD compatible with a non-stick buttpad letting the shooter dial in length of pull quickly and mount a sling without fuss. Finished with a black polymer grip and stock for a cohesive purpose-built look the StealthMS5 is a complete ready-to-run integrally suppressed rifle for sale at GrabAGun.
