Description
HM Defense built the Defender M5 with shooters in mind—a straightforward, reliable 5.56 NATO platform that doesn’t cut corners where it counts. The 16″ 4150 chrome moly match-grade barrel pairs with a mid-length gas system for smooth operation and predictable accuracy, while the 7075-T6 aluminum receivers are hard-coat anodized for durability. You get a 10.37″ free-float M-LOK handguard that stays rigid under optics and accessories, mil-spec trigger and controls, and a proven M16 bolt carrier group. Whether you’re building a home-defense rifle, a competition gun, or a reliable trainer, this comes ready to shoot with furniture in place and one magazine included.
