SIG Sauer Spr 556 5.56 NATO 11.5" 30-Round Threaded Barrel Carbine

The SIG Sauer SPR 556 5.56 NATO 11.5" 30-Round Threaded Barrel Carbine is purpose-built for operators who demand compact firepower without sacrificing combat effectiveness. Designed for tactical teams, law enforcement specialists, and military units requiring a short-barreled rifle platform, this carbine delivers the ballistic performance of 5.56 NATO in a configuration optimized for close-quarters and vehicle operations. The 11.5" barrel length provides rapid target engagement capability while maintaining velocity sufficient for duty-grade ammunition performance at typical engagement distances.

Built on SIG Sauer's proven MCX platform architecture, this rifle features a threaded muzzle (1/2x28 thread pitch) for direct attachment of sound suppressors, compensators, or flash hiders—essential for tactical noise signature management and muzzle control. The 30-round magazine capacity ensures adequate firepower for extended engagements, while the flat dark earth finish provides non-reflective concealment across varied operational environments. Precision-engineered receiver tolerances and cold-hammer-forged barrel construction deliver reliability that meets military and law enforcement specifications under sustained fire and adverse conditions.

This configuration benefits tactical operators, SWAT teams, and military personnel who operate in confined spaces where barrel length directly impacts maneuverability and target acquisition speed. The threaded barrel enables seamless integration with industry-standard suppressors for hearing protection and signature reduction—critical in dynamic entry scenarios and sustained operations. Law enforcement specialists appreciate the compact profile for vehicle transport and building clearance, while the 30-round magazine capacity ensures force-on-force readiness without frequent reloading cycles common to shorter-capacity platforms.
