Sig Sauer Minimalist Plus Folding Stock - Coyote Brown Aluminum, Fits MPX/MCX, 9" OAL (Model 8901268)

The Sig Sauer Minimalist Plus folding stock is a lightweight, no-nonsense accessory built for shooters running an MPX or MCX platform. This aluminum stock mounts directly to your rifle's Picatinny receiver interface and folds for compact storage, transport, or when you need to move through tight spaces. At just 9 inches overall length when extended, it delivers a traditional cheek weld height without the bulk of a fixed or heavy collapsible design. The Coyote Brown finish matches the color palette of modern tactical rifle builds and holds up to field use.

Constructed from aluminum, the Minimalist Plus is engineered to take hard use. The buttpad width of 0.9 inches provides a solid surface against your shoulder, and at 12.3 ounces, the stock won't tip the scales or throw off your rifle's balance. Installation is straightforward if you're familiar with Picatinny-mounted accessories—no additional tools or gunsmithing required. The folding mechanism lets you collapse the stock when you need a shorter profile, making it popular with hunters, operators, and range shooters who value adaptability.

Before purchasing, confirm that a folding or collapsible stock is legal in your state and locality. Regulations vary widely, and it's your responsibility to verify compliance with all federal, state, and local laws before possession or use. The Minimalist Plus is purpose-built for Sig's MPX and MCX platforms, so compatibility with those systems is a given—just verify your specific model variant (MCX-SPEAR, MCX-SPEAR LT, or MPX) uses a Picatinny interface.
