Mitchell Defense DOC 12.5" MD15 | 5.56 Patrol SBR

The Mitchell Defense DOC 12.5" MD15 5.56 Patrol SBR is a short-barreled rifle chambered in 5.56 NATO and built around a 12.5-inch cold hammer forged, chrome-lined barrel with a 1:7 twist. The rifle uses a carbine-length, non-adjustable direct-impingement gas system paired with the MD Carbon Cutter BCG with ArmorLube coating. A black DualCool CP1 M-LOK handguard incorporates an additively manufactured, air-gapped structure designed to reduce heat transfer to shooter-contact surfaces.

The DOC 12.5" MD15 also features the Mitchell Defense A5 recoil system, combining an MD A5 receiver extension, rifle-length flat-wire spring, and MD A5 buffer. Additional components include a Reptilia Puller, Radian Talon safety selector, ambidextrous bolt release, two-stage trigger, B5 stock and furniture, and QD end plate. This configuration includes three Lancer magazines and one black Ryker Sling, providing a packaged 12.5-inch 5.56 SBR configuration for patrol, training, and general-purpose applications.
