Sig Sauer MCX Spear LT 300 Blackout 9" Pistol Brace FDE

Sig Sauer MCX Spear LT 300 Blackout 9" Pistol Brace FDE

The Sig Sauer MCX Spear LT is a compact semi-automatic pistol chambered in 300 Blackout and built around a 9-inch threaded barrel. This configuration combines the modular MCX platform with fully ambidextrous controls, a SIG flat blade match trigger, pistol brace, and a durable Flat Dark Earth Cerakote finish.

Designed for a compact footprint without sacrificing the features of the MCX platform, the Spear LT uses SIG's receiver and operating-system architecture that eliminates the need for a traditional AR-style buffer tube. This configuration includes a 30-round magazine and factory pistol brace.

9" 300 Blackout Barrel

The 9-inch threaded barrel provides a compact configuration specifically chambered for 300 Blackout. The threaded muzzle allows the use of compatible muzzle devices and other properly matched muzzle accessories.

Fully Ambidextrous Controls

The MCX Spear LT features fully ambidextrous controls, providing convenient operation from either side of the firearm and contributing to the platform's adaptable design.

SIG Flat Blade Match Trigger

A factory SIG flat blade match trigger provides a clean, consistent trigger interface and complements the performance-oriented design of the Spear LT platform.

Gen II IR Cerakote Finish

This MCX Spear LT features Cerakote Gen II IR coating in Flat Dark Earth. According to SIG, the IR coating is designed to provide reduced visibility under thermal or night-view equipment while also providing wear and corrosion resistance in adverse conditions.

Compact MCX Platform

The MCX architecture allows the firearm to operate without a traditional AR buffer tube extending behind the receiver. Combined with the pistol brace and 9-inch barrel, this gives the Spear LT a compact overall configuration while retaining the modular characteristics of the MCX family.
