Sig Sauer 8901458 Mcx/Mpx Stock Coyote Brown Aluminum Folding

The Sig Sauer MCX/MPX folding stock in coyote brown delivers the modularity and compact handling that makes these platforms so popular with tactical shooters, hunters running short-barrel setups, and anyone who values flexibility. Built from aluminum, this stock collapses when you need it—ideal for vehicle storage, tight spaces, or quick transitions—then locks solid when extended for a full cheek weld and consistent sight picture.

Whether you're running an MCX or MPX, this factory Sig piece integrates seamlessly with your platform's controls and geometry. The coyote brown finish matches the aesthetic of modern tactical rigs while providing a durable, low-glare surface that won't stand out in the field or on the range.

This is a genuine Sig OEM component engineered to the same specs as the stock systems Sig builds on MCX and MPX rifles straight from the factory. If you're upgrading, replacing a worn original, or configuring a new upper on your existing lower, you're getting the fit and reliability you expect from Sig's own platform.
