Mitchell Defense DOC 10.3" MD15 | 5.56 CQB SBR

The Mitchell Defense DOC 10.3" MD15 5.56 CQB SBR is a compact short-barreled rifle chambered in 5.56 NATO and configured around a 10.3-inch cold hammer forged, chrome-lined barrel with a 1:7 twist. Its carbine-length, non-adjustable direct-impingement gas system is paired with the MD Carbon Cutter BCG with ArmorLube coating. The rifle also features Mitchell Defense's black DualCool CP1 M-LOK handguard, which uses an additively manufactured, air-gapped structure designed to reduce heat transfer to shooter-contact surfaces.

The DOC 10.3" MD15 incorporates the Mitchell Defense A5 recoil system, consisting of 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 also includes three Lancer magazines and one black Ryker Sling, creating a packaged 10.3-inch MD15 configuration for applications where a shorter overall platform is preferred.
