SIG SAUER MCX SPEAR-LT SBR 5.56 NATO 11.5" IR Cerakote – RMCX-556N-11B-IR-SBR
The SIG SAUER MCX SPEAR-LT SBR in 5.56 NATO delivers a compact, mission-ready rifle built on the next generation of the legendary MCX platform. Featuring an 11.5-inch barrel, this short-barreled rifle offers excellent maneuverability without sacrificing the accuracy and reliability shooters expect from SIG’s piston-driven system. Finished in IR Cerakote, the rifle provides enhanced durability and reduced signature for professional or tactical use.
At the core of the MCX SPEAR-LT is SIG’s short-stroke gas piston system, which keeps the action running clean and reliable even in demanding conditions. The rifle features a lightweight M-LOK aluminum handguard, fully ambidextrous controls, and a match-grade flat trigger, giving shooters excellent ergonomics and precision. The side-folding stock allows for easy storage and transport while maintaining full functionality when folded.
Designed for modern shooters, the MCX SPEAR-LT is fully optic-ready and suppressor compatible, making it an ideal platform for tactical professionals, enthusiasts, or collectors seeking one of SIG SAUER’s most advanced rifles. Whether configured for duty use, defensive applications, or range performance, the MCX SPEAR-LT SBR represents the evolution of the MCX family with improved weight, balance, and modularity.
