Mk12-Style 18-inch DD S2W on a Radian A-DAC Lower

A Mk12-inspired 18-inch rifle on a BCM M4 upper and a Radian A-DAC ambidextrous lower, with a Daniel Defense CHF S2W rifle-length barrel under a 12.25-inch RIS II and a Badger Mk12 gas block. It wears a Nightforce NXS 2.5-10x42 in Badger C.O.M.M. rings, a Geissele SSA-E, an LMT SOPMOD stock, a SureFire SOCOM RC2 and a Harris bipod. The builder says it isn't meant to be a clone.
