Sig Sauer MCX Spear LT 16" 5.56 NATO

The Sig Sauer MCX Spear LT continues the innovation of the legendary MCX platform, delivering a lightweight yet robust design. Chambered in 5.56 NATO, this rifle is equipped with a folding buffer borrowed from the full-size Spear, a B5 Bravo stock for enhanced ergonomics, and a durable 16" barrel with a 1:7" twist for excellent accuracy.

Upgrades from the MCX Virtus include fewer screws on the handguard for better cooling, enhanced rigidity to minimize barrel flex, and ambidextrous controls for superior flexibility. The flatblade match trigger ensures a crisp break, while the slim profile and lightweight handguard make it easy to handle in any environment.

Finished in coyote cerakote for a rugged and professional look, the Spear LT also features an ambidextrous bolt catch/release and is fully compatible with AR-15 magazines. Whether for tactical applications or range use, the MCX Spear LT offers unparalleled adaptability and performance.
