The Daniel Defense SPRIII 5.56mm rifle represents the modern evolution of the iconic MK12 Special Purpose Rifle, blending proven long-range precision with contemporary upgrades tailored for today's discerning marksmen. At its foundation lies an 18-inch cold hammer-forged stainless steel barrel in the classic MK12 profile, finished with a durable DLC coating and featuring a 1:7 twist rate for exceptional stability and accuracy at extended distances. Paired with a rifle-length gas system and low-profile gas block, the SPRIII delivers remarkably soft recoil and consistent cycling, making follow-up shots faster and more precise whether on the range, in competition, or in precision tactical applications. Daniel Defense elevates the platform with a robust 15-inch RIS III M-Lok handguard that incorporates an integrated ARCALOCK bottom section, providing a rock-solid mounting surface for bipods, tripods, bags, and other accessories without added weight or complexity. The fully ambidextrous lower receiver offers intuitive controls-including safety selector, mag release, and bolt catch-ensuring seamless operation for left- and right-handed shooters alike. Complementing these enhancements are the match-grade Geissele SSA trigger for crisp, predictable breaks and the adjustable Magpul PRS Lite stock that allows fine-tuned length of pull and cheek weld for maximum stability and shooter comfort. Built with premium mil-spec 7075-T6 aluminum receivers, a chrome-lined M16-profile bolt carrier group, and a Daniel Defense flash suppressor, the SPRIII maintains legendary reliability while weighing in at just 8.6 pounds. It ships complete with a 32-round Daniel Defense magazine and a rugged full-latch impact plastic case, ready for immediate use. This rifle stands as the pinnacle of semi-automatic precision shooting, offering unmatched accuracy, modularity, and refinement for serious enthusiasts and professionals.
