The Daniel Defense DDM4 MK12 SPR is built around an 18-inch MK12-profile barrel and a rifle-length gas system for accuracy-focused performance. It features a free-floating 12.0-inch DDM4 quad rail, Geissele SSA 2-stage trigger, and Daniel Defense fur

The Daniel Defense DDM4 MK12 SPR is a purpose-built modern sporting rifle centered on an 18-inch MK12-profile barrel and a rifle-length gas system. The rifle is fitted with a 12.0-inch free-floating DDM4 rail that accepts optics and accessories, and it ships with Daniel Defense furniture including a 6-position receiver extension and soft-touch overmolding on the stock and grip. For an optic under $1,000 that pairs well with this platform, consider a Vortex Strike Eagle 1-6×24, which provides a versatile magnification range for both close work and extended precision at moderate ranges.
