The SIG SAUER MCX / MPX Folding and Telescoping Stock – Coyote is a factory OEM stock assembly designed to upgrade or replace the stock on MCX, MCX-SPEAR LT, and MPX platforms. Built for durability, modularity, and compact storage, this stock combines a side-folding hinge with a multi-position telescoping design to provide shooters with maximum adaptability for different shooting styles and gear setups.

The stock attaches directly to firearms equipped with a 1913 Picatinny rear interface, allowing quick installation without permanent modification. Its five adjustable length positions allow users to fine-tune length of pull for improved ergonomics, recoil control, and comfort whether shooting with armor, chest rigs, or lightweight range gear.

Constructed from a combination of high-strength aluminum and reinforced polymer, the stock provides excellent strength while remaining lightweight at approximately 14.1 ounces. The folding mechanism reduces the firearm’s overall footprint for easier storage and transport while maintaining a solid lockup when deployed.

Integrated Quick Detach (QD) sling attachment points allow easy mounting of sling systems, making the stock suitable for duty use, training, or defensive rifle setups. The Coyote finish complements modern rifle builds and matches many tactical accessories and equipment setups.

This factory SIG SAUER stock delivers the rugged reliability and modular design expected from one of the most trusted manufacturers in modern firearms accessories.
