SIG MCX/MPX FLDING/TLSCPING STK FDE

Description

The Sig Sauer MCX/MPX Folding and Telescoping Stock in Flat Dark Earth is designed for shooters who run the MCX or MPX platform and want a full shoulder stock that collapses for transport and folds entirely out of the way when space is at a premium. The folding hinge locks the stock securely against the receiver, keeping the rifle or pistol-caliber carbine compact without requiring any tools or disassembly.

The telescoping function gives you adjustable length of pull, so you can dial the fit to your body or accommodate different clothing and gear setups without being locked into a single position. That kind of adjustability matters when the same rifle is used in different roles or by different shooters. The stock is purpose-built by Sig Sauer for the MCX and MPX action interface, so the fit and lockup are direct and solid rather than relying on an adapter arrangement.

Flat Dark Earth is Sig’s own designation for this finish, matching the FDE hardware options available across the MCX and MPX accessory line so you can keep the build visually consistent. The stock installs directly onto compatible MCX and MPX receivers and does not require modification to the host firearm. If you’re building out a dedicated MCX or MPX configuration with a genuine Sig component rather than a third-party substitute, this is the stock the platform was engineered around.
