Description
DS-15 M4 Maryland HBAR Rifle
The DS-15 M4 Maryland HBAR Rifle combines classic M4 styling with a purpose-built heavy-barrel configuration for Maryland customers. Built on a precision-matched forged receiver set, the rifle features traditional M4 furniture, standard AR-15 controls, an F-height A2 front sight base, and a removable carry handle for a familiar military-inspired configuration.
At the center of the rifle is a 16-inch HBAR-profile 5.56 NATO barrel manufactured from premium 4150 CMV steel. The barrel features a 1:9 twist, carbine-length gas system, and black nitride finish. An A2 birdcage flash hider completes the traditional M4 appearance.
For Maryland customers searching for a Maryland HBAR AR-15 with classic styling rather than a modern free-float configuration, the DS-15 M4 provides a factory-built heavy-barrel rifle with the familiar carry handle, front sight post, and M4 furniture that define the platform.
Available Finish: Black Anodized
Every firearm is hand-assembled and individually tested at our factory in Rockledge, Florida using American-made components and materials.
