Sig Sauer, Mcx Spear Light, 5.56 Nato, 11.5 inch, 30 round, Flat Dark Earth Cerakote

The Sig Sauer PMCX556N11BIR MCX Spear LT brings the MCX Spear LT series into a compact, mission-capable package chambered in 5.56 NATO with an 11.5-inch cold hammer-forged carbon steel barrel and a 1:7 twist that stabilizes a wide range of 55—77 grain projectiles for duty, range, and lightweight patrol use. Designed around Sig's proven gas piston operating system and an adjustable gas block, this semi-auto rifle runs reliably on suppressed or unsuppressed setups and features 1/2-28 threading for common muzzle devices and a QD flash hider for quick recoil signatures. The Gen II NiR FDE Cerakote receiver and alloy forend with M-LOK attachment points provide corrosion resistance and modular mounting for lights, optics, and other mission-essential accessories while the folding PCB brace with push-button hinge reduces stored length to 26.25 inches for transport without sacrificing a 29.75-inch overall reach when deployed. Ambidextrous controls, a SIG flat blade match trigger, polymer grip, alloy steel receiver, and an AR-15 style magazine interface make it familiar to AR users but more robust under prolonged use; this rifle is ideal for tactical teams, home defense-minded shooters, and precision-oriented carbine enthusiasts who need a reliable, compact 5.56 platform that accepts common parts and accessories and requires FFL transfer compliance.
