Sig Sauer MCX Spear | 7.62 Nato | 16" | MultiCam | 20rd Rifle

The SIG Sauer MCX Spear represents the pinnacle of modern battle rifle development. Born directly from the technology submitted for the U.S. Army’s Next Generation Squad Weapon program, this civilian-legal semi-automatic adaptation brings combat-proven durability and bleeding-edge ergonomics to the commercial market.

Chambered in the hard-hitting 7.62x51mm NATO caliber, this model features a factory MultiCam Cerakote finish, ensuring high-tier environmental concealment paired with elite tactical utility.

Short-Stroke Piston Reliability & Multi-Caliber Versatility

At the core of the MCX Spear is SIG’s legendary short-stroke gas piston operating system. By venting expanding gases away from the bolt carrier group and out of the forward gas block, the rifle runs cooler, cleaner, and with drastically enhanced component life compared to traditional direct-impingement systems.

• Adjustable Gas Valve: Features a two-position adjustable gas regulator, allowing you to instantly optimize gas flow for unsuppressed training or suppressed tactical deployment.

• True Modular Design: The MCX Spear is designed for adaptability. The user-interchangeable barrel system allows operators to swap calibers down the line with standard tools, expanding utility beyond the factory configuration.

Revolutionary Dual-Charging Architecture

To accommodate any tactical posture or user preference, the MCX Spear is outfitted with two independent, non-reciprocating charging mechanisms.

• Traditional Rear Handle: An AR-style charging handle at the rear of the receiver allows standard manipulation familiar to anyone trained on the M4 or M16 platform.

• Left-Side Folding Handle: A side-mounted, folding charging handle allows you to cycle the action or clear a malfunction quickly while keeping your master grip intact and keeping your eyes downrange.

Built for Absolute Ambidextrous Control

No matter your shooting position, the MCX Spear provides flawless ergonomics. The bolt catch and bolt release are mirrored on both sides of the receiver, permitting rapid reloads without needing to shift your support hand. Paired with a smooth 2-stage match trigger and a folding stock that locks securely into place, the rifle easily compresses down for storage or vehicle operations while maintaining a rigid platform for long-range target engagement.
