Product Overview

Product Description

The SIG SAUER MCX-SPEAR LT IR builds on the MCX platform with a lightweight, modular design and reduced IR signature. Finished in Gen II FDE Cerakote with IR-reducing properties, the rifle is designed to minimize visibility under night vision and thermal while providing added wear and corrosion resistance.

The SPEAR LT features a lightweight handguard, fully ambidextrous controls, SIG's Flatblade Match Trigger, interchangeable barrel system, and a Rocksett®-secured SIG QD suppressor-ready flash hider. The Tele-Fold stock keeps the rifle compact for storage and transport without sacrificing shooting comfort.

    Sig Spear 300 BLK

    Posted by Jonathon Roedding on Sep 8th 2026

    This is a premium, purpose-built .300 BLK SBR rather than just an AR with a short barrel. If the goal is a compact, suppressor-oriented rifle with excellent controls and a proven piston architecture, the 9" SPEAR LT is arguably one of the strongest configurations in the MCX lineup. For me, the combination of the 9-inch barrel, .300 BLK and folding-stock MCX architecture is really the sweet spot of the platform.
