Design and Controls

The SIG SAUER MCX SPEAR is the civilian counterpart to the Army’s XM7 and brings true ambidexterity to a lightweight, suppressed-capable platform. Key features include fully ambidextrous controls with an ambidextrous bolt catch and bolt release, plus non-reciprocating rear and side charging handles for maximum flexibility when using optics or shooting from unconventional positions.

Ambidextrous features

The Matchlite Duo Trigger provides a clean, crisp break suitable for precision follow-up shots.

Shooting and Suppression

The MCX SPEAR ships with SIG’s SLX/SLH QD flash hider and a 2-position adjustable gas valve that permits reliable cycling when shooting suppressed or unsuppressed. The non-reciprocating charging handles allow optics clearance while the adjustable gas system keeps dwell and recoil consistent across configurations.

Modularity, Stock and Barrel Options

This rifle is built with caliber conversion and user adaptability in mind: an interchangeable barrel system simplifies conversions, and the folding 6-position Magpul SL-M stock folds for compact carry while offering six full length adjustments for shooter fit. The rifle ships with one 20-round magazine and arrives coyote tan anodized for a low-reflective finish.

Price sits at $3999.99, reflecting its next-generation design and factory-ready suppressor compatibility. Shop this product
