Sig Sauer 8901411 Minimalist Plus Black Aluminum Fits Mpx/Mcx Folding 9" Oal

The Sig Sauer Minimalist Plus folding stock is a lightweight aluminum alternative for MCX and MPX platform owners who want modularity without bulk. Built to attach via standard Picatinny rail interface, this stock folds for compact transport and stowed profiles while maintaining a traditional buttpad height for consistent shooting geometry. It's the kind of upgrade that appeals to shooters running short-barreled rifles, truck guns, or any setup where space is at a premium.

At 9 inches fully extended and just 12.3 ounces, the Minimalist Plus keeps weight down while its aluminum construction resists corrosion and abuse. The design is straightforward—no levers or complications—and the folding mechanism lets you collapse the stock when you're moving through tight spaces or packing gear. Whether you're prepping a home-defense MCX, a duty-ready MPX, or a dedicated range gun, this stock delivers practical functionality without excess.

Before you buy, verify your local and state laws regarding folding stocks. Regulations vary by jurisdiction, and it's entirely your responsibility to ensure this stock complies with the laws where you live and shoot. Some states and localities restrict or prohibit folding stocks, especially in combination with certain other features. Do your homework first.
