Product Description

The HM Defense DefenderM556 is a highly accurate and reliable rifle that boasts of several key features that make it stand out from other rifles on the market. At the heart of this rifle is the HM patented MONOBLOC HBAR barrel that has an integrally machined gas block. The barrel is chambered in 5.56 NATO/223 Rem, has a length of 16 inches, a 1:8 twist ratio, and a mid-length gas system. The 4150 Chromoly barrel is match grade, tripled honed, and button rifled to ensure superior accuracy.

The custom HM Defense 10 3/8" inch, free float 1913 Picatinny rail is CNC machined from 6061-T6 aircraft grade aluminum and is compatible with the Magpul M-LOK mounting system. This rail allows for the easy attachment of accessories such as scopes, sights, and other tactical gear.

The lower receiver is a Mil-Spec Forged 7075-T6 with a Type III Class I hard-coat black anodized finish. The upper receiver is also a Mil-Spec Forged 7075-T6 M4 with a Type III Class I hard-coat black anodized finish, M4 Feed Ramps, and a 1913 Picatinny rail flat top. This gives the rifle a sleek and durable finish.

The rifle includes a M16 bolt carrier group with patented HMB bolt and Mil-Spec components, including the trigger & fire control group, charging handle, and buffer tube/spring. The custom Trigger Guard, Monobloc Dust Cover, and CNC Machined Muzzle Brake make this rifle a reliable and high-performing machine.

HM Defense rifles feature a custom Quick Disconnect (QD) end plate and black Mil-Spec HM stock and enhanced grip. A magazine is included with each rifle, making it ready to use right out of the box.
