I have a new in case Daniel Defense SPRIII for sale. Not had a round down the barrel, only had a few through the magazine to check feed/extraction/ejection. In original case with manual, lock, and 32rd Daniel Defense magazine.
At its core, the SPRIII retains the 18" stainless MK12-profile barrel and rifle-length gas system that made the MK12 renowned for its accuracy and soft recoil. Building on that foundation, Daniel Defense has introduced a new 15" RIS III rail with an integrated ARCALOCK section for extended bipod and accessory mounting. A Geissele Super Semi-Automatic (SSA) trigger ensures match-grade consistency, while the new Magpul PRS Lite stock provides stability and adjustability. The new fully ambidextrous lower rounds out the upgrades, making the SPRIII the evolution of precision.
Asking $2400 Venmo as goods and services. I will handle shipping.
