Description

Modernizing a Combat Legend: The Next-Generation SPR The MK12 Special Purpose Rifle platform set the standard for military precision and reliability. The Daniel Defense SPRIII honors that legacy while introducing critical technological upgrades required by modern marksmen and law enforcement sniper elements. Retaining the renowned 18-inch stainless MK12-profile barrel and rifle-length gas system, the SPRIII delivers exceptionally smooth, low-recoil cycling and superior velocity stabilization for heavy 5.56mm match loads (such as Mk262) at extended distances.

Advanced Precision Engineering & Ergonomics

RIS III 15.0 with ARCALOCK: The extended 15-inch RIS III handguard features a fully integrated ARCALOCK bottom rail. This provides a rock-solid, multi-position interface for precision tripods, bipods, and shooting bags, enabling lightning-fast adjustments in dynamic field environments.
Geissele SSA Match Trigger: Factory-equipped with a Geissele Super Semi-Automatic (SSA) two-stage trigger, providing a crisp, predictable break that maximizes shooter accuracy and control.
Fully Ambidextrous Controls: Features a fully ambidextrous lower receiver, allowing operators to manipulate the safety selector, charging handle, magazine release, and bolt release from any shooting position without breaking their firing grip.
Magpul PRS Lite Stock: Provides robust stability and user-adjustable length-of-pull and cheek height to ensure a custom, repeatable fit for every operator.

Important Procurement Note (Optics & Sights) The SPRIII is engineered as a dedicated precision platform; factory iron sights and scopes are sold separately. When constructing agency RFPs or departmental DMR upgrade packages, procurement officers should ensure that precision optics (such as variable magnification scopes), bipods, and ARCALOCK mounting adapters are explicitly included in the fulfillment request.
