The SIG MCX-SPEAR LT 5.56 IR 16″ rifle represents the pinnacle of modern firearm engineering, blending advanced technology with modular versatility. Designed for both civilian shooters and tactical professionals, this rifle stands out. Based on the rifle chosen in the military NGSW program, the SIG MCX-SPEAR LT 5.56 IR is a chance to own what soldiers will carry.

SIG-MCX-SPEAR-LT-5.56-IR-16″-Rifle – Innovative Design and Build

At the heart of the MCX-SPEAR LT is its lightweight, monolithic upper receiver, crafted from high-strength aluminum. This design reduces weight and enhances the rifle’s rigidity and accuracy. The rifle’s 16-inch cold hammer-forged barrel boasts a 1:7 twist rate, optimized for stabilizing a variety of 5.56 NATO ammunition types, ensuring consistent performance across different loads.

One of the standout features of the MCX-SPEAR LT is its short-stroke gas piston operating system. This system offers cleaner operation compared to traditional direct impingement systems, leading to increased reliability and reduced maintenance. Coupled with a flat-blade Matchlite Duo trigger, the rifle delivers a crisp, responsive shooting experience, enhancing accuracy and shooter confidence.

Ambidextrous Controls and Ergonomics

The MCX-SPEAR LT is engineered with fully ambidextrous controls, including the safety selector, charging handle, magazine release, and bolt catch/release. This thoughtful design ensures that left- and right-handed shooters can efficiently operate the rifle. The telescoping and folding stock, equipped with a push-button locking mechanism, allows for quick adjustments to fit various shooting positions and storage requirements.

The rifle’s ergonomic M-LOK-compatible handguard provides ample space for accessories while maintaining a slim profile. The reduced-angle polymer grip contributes to a natural wrist alignment, reducing shooter fatigue during extended use.

Tactical Features for Modern Operations

Designed for tactical operations, the MCX-SPEAR LT features a Gen II Night Infrared (NiR) Cerakote finish in Flat Dark Earth (FDE). This advanced coating reduces the rifle’s infrared signature, making it less detectable under thermal imaging, a crucial advantage in low-visibility environments.

The rifle has a suppressor-ready, quick-detach flash hider compatible with SIG’s SLX suppressor line. This feature allows for seamless suppression integration, enhancing stealth and reducing muzzle flash during operations.

Modularity and Customization

True to SIG Sauer’s commitment to modularity, the MCX-SPEAR LT offers interchangeability with all MCX-LT barrels and handguards. This flexibility enables users to adapt the rifle to various mission requirements by changing barrel lengths or handguard configurations without the need for specialized tools.

The rifle’s design also accommodates standard AR-15 magazines, further enhancing its versatility and compatibility with widely available accessories.

Performance and Handling

On the range, the MCX-SPEAR LT is a serious shooter. It is everything you would expect from Sig. The harsh, sharp angles were eliminated, and running it was a comfortable affair. The trigger on the Spear made for quick initial shots and faster follow-ups. This is the civilian version in many ways of the gun our frontline warriors will be using. After running it hard, I can see why. It ran flawlessly and gave me solid accuracy, even in motion and at pace. The folding stock is made for easy storage and makes it a contender for a truck gun.
