Sig Sauer MCX Spear LT 5.56 NATO 11.5" 30rd FDE SBR

This is the registered short barrel rifle version of the MCX Spear LT IR, chambered in 5.56 NATO with an 11.5" cold hammer forged barrel and a 1:7 twist. The muzzle is threaded 1/2-28 and carries a Sig QD flash hider that is ready for Sig suppressors. The MCX short stroke gas piston runs without a buffer tube, so the telescoping stock folds against the receiver, and the gas system is adjustable for suppressed and unsuppressed shooting.

Controls are fully ambidextrous, the trigger is the Sig flat blade match unit, and the lightweight alloy handguard has M-LOK slots. Barrels are interchangeable. It takes standard AR-15 magazines and comes with one 30 round polymer magazine. The receiver is finished in Gen II NIR Flat Dark Earth Cerakote, which reduces visibility under night vision and thermal and adds wear and corrosion resistance. It has a forward assist.
