Mitchell Defense DOC 7.5" MD15 | .300 BLK SBR

The Mitchell Defense DOC 7.5" MD15 .300 Blackout SBR is a compact short-barreled rifle configured for .300 BLK and suppressed applications. It features a 7.5-inch stainless steel barrel with a fast 1:5 twist rate designed to accommodate heavy subsonic projectiles. A pistol-length, adjustable direct-impingement gas system provides the ability to tune operation for different ammunition and suppressor configurations, while the MD Carbon Cutter BCG with ArmorLube coating serves as the rifle's bolt carrier group.

The DOC 7.5" MD15 is equipped with a black DualCool CP1 M-LOK handguard, featuring an additively manufactured, air-gapped design intended to reduce heat transfer to shooter-contact surfaces. Its buffer system uses a carbine-length buffer tube with a lightweight buffer spring, while additional components include a Reptilia Puller, Radian Talon safety selector, ambidextrous bolt release, two-stage trigger, B5 stock and furniture, and QD end plate. The package also includes three Lancer magazines and one black Ryker Sling.
