Sig Sauer MCX Spear LT IR 5.56 NATO 16" 30+1 Semi-Auto Rifle - FDE

The Sig Sauer MCX Spear LT IR is a semi-automatic tactical rifle chambered in 5.56 NATO that continues the proven MCX Virtus lineage in a lighter, more compact configuration. Built around a tough alloy steel receiver finished in Black FNC, it is paired with a Flat Dark Earth anodized aluminum telescoping folding stock.

A 16" threaded steel barrel with a 1:7" twist rate sits beneath a lightweight ergonomic handguard. The rifle ships without iron sights, leaving the full-length optics rail open for your preferred red dot, low-power variable, or clip-on thermal/night-vision device. The muzzle is fitted with Sig Sauer's QD suppressor-ready flash hider for straightforward suppressor mounting.

Sig Sauer equipped the MCX Spear LT IR with fully ambidextrous controls, including an ambidextrous safety lever for natural left- or right-handed operation. A crisp flat blade match trigger delivers a clean break for improved accuracy. The rifle measures 35" overall and weighs approximately 7.50 lbs, with a 30+1 capacity from a single 30-round detachable magazine.
