Design & Controls

Ambidextrous Controls

The SPEAR’s fully ambidextrous controls, including safety and bolt release, ensure smooth handling for both right- and left-handed shooters. That design choice reduces transition time in dynamic scenarios and improves weapon retention and manipulation under stress.

Dual Non-Reciprocating Charging Handles

Two charging handles — one side-mounted for rapid access and a traditional rear-mounted option — provide unmatched versatility. The non-reciprocating design eliminates interference with mounted optics and hand placement during operation.

Barrel, Trigger, and Reliability

The Chrome Lined DLC barrel is engineered for enhanced durability, heat resistance, and extended service life, making the SPEAR suitable for high-round-count training and operational deployments. Complementing the barrel is a two-stage match trigger that delivers a crisp, consistent break for improved shot-to-shot precision.

Applications and Practicality

Based on the NGSW rifle concept, the SIG SAUER MCX SPEAR bridges modern military specs and practical civilian applications: mission-focused training, competitive shooting, and defense-minded ownership. At a price point of $4599.99, it sits in the premium bracket for shooters prioritizing cutting-edge features and hardware built to military-derived standards.
