    • One 10-round Magpul PMAG LR/SR Gen M3 polymer magazine for 7.62×51

    The DB10 follows the AR-10/LR-308 pattern and uses SR-25/DPMS-pattern magazines. It has a capacity of 10+1 and comes with a Magpul PMAG LR/SR Gen M3 included. The lower is marked "CAL. MULTI" and the ejection port cover is marked "308 WIN" for clear chamber identification.

    The 16-inch barrel is threaded, ready for common muzzle devices, and is surrounded by a free-float aluminum M-LOK handguard with short top Picatinny sections for accessory placement. A continuous Picatinny rail on the upper receiver provides mounting space for optics or backup sights as needed.

    Controls and receiver features include an ambidextrous safety selector, a single-stage curved trigger, a standard magazine release, a forward assist, and a case deflector. The forged upper carries an "A" forging mark. The rifle ships without sights, allowing the end user to configure to preference.

    Magpul furniture rounds out the package with an adjustable MOE stock and MOE pistol grip, delivering a listed length of pull of 14.25 inches. The rifle is finished in matte black and is made in the USA.
