Daniel Defense MK12 AR-15 SPR 5.56 NATO/.223 Rem 18" Rifle


Product description

Born of necessity, the evolution of the SPR comes home in the MK12 by Daniel Defense. Constructed around an 18" stainless steel cold hammer-forged barrel, the Daniel Defense MK12 rifle features precise alignment of the chamber to the bore. Some of the most durable barrels available, the barrels are bead blasted and chemically passivated in order to resist corrosion. Engineered with a rifle-length direct impingement gas system, the rifle utilizes the MK12 gas block system, built to Crane Specifications for USSOCOM and is precision CNC machined from 416 stainless steel and black oxide coated. The upper receiver is fed with an M16 profile BCG, utilizes a Vltor Mod 4 charging handle, and is equipped with a free-floating DDM4 Rail 12" allowing for the operator's choice of optics and accessories.
