Sig Sauer MCX Spear 7.62x51 NATO 13" Coyote Tan 20+1 PSPEAR-762-13B

Sig Sauer MCX Spear

The Sig Sauer MCX Spear is a semi-automatic gas piston AR pistol chambered in 7.62x51mm NATO. It includes a 13-inch black finished barrel with a 1:10 twist rate for reliable stabilization of 7.62 NATO loads. The Coyote Cerakote receiver and furniture deliver corrosion resistance along with a cohesive field aesthetic. A 20+1 capacity is supported through AR-10 magazine compatibility. Overall length measures 24.50 inches and weight is listed at 9.20 lbs.

The gas piston operating system runs cleaner and cooler than direct impingement designs during sustained fire or suppressed use. An M-LOK free-float handguard provides a rigid mounting platform for lights, lasers, and accessories without contacting the barrel. The included QD flash hider is threaded 5/8-24 for immediate suppressor readiness and muzzle management. Ambidextrous manual safety and coyote polymer grips support comfortable handling for both left and right handed shooters across extended sessions.

This configuration suits tactical applications and precision focused range use with the full power 7.62x51mm cartridge. The mass and balance help control recoil impulse for accurate follow up shots. Shooters seeking the MCX platform in a pistol format with suppressor ready features and modern ergonomics will find the design well matched to demanding requirements.
