M21DMR Bushmaster




SKU: N/A Category:


DMR stands for Designated Marksman Rifle, and the M21DMR Bushmaster is designed to provide the enhanced performance and long range accuracy needed to fill this role. A 20″ heavy profile 450 Bushmaster barrel, combined with integrated optic rail takes the M14 platform to a higher level of performance.

This is the M21DMR designation of the Bula Defense M14 rifle that incorporates a rock solid picatinny rail on top of the receiver in addition to the traditional iron sights. The rail is hollowed out down its’ length allowing the ability to view the iron sights with the rail attached. Pending scope size, the iron sights may also co-witness with the scope. Rails are precision aligned along the center-line of the barrel to provide exceptional accuracy when mounting optics.

The barrel features a 20” heavy profile, significantly reducing barrel whip. The muzzle features a 11/16”-24 threaded brake. The tactical stock features an M-Lok for-end, adjustable cheek riser and adjustable length of pull. The rifle comes standard with a Bula Defense Muzzle Brake.

Features: Bula Defense forged XM21 receiver with MIL-SPEC components; gas operated, piston driven semi-automatic action; and one (1) 5 round box magazine, Bula Forge muzzle brake.
