Sig Sauer 8901410 Minimalist Black Aluminum Fits Mpx/Mcx Folding 9" Oal

The Sig Sauer Minimalist folding stock is a compact, aluminum-built option purpose-designed for MCX and MPX platforms. If you run a Sig piston gun and need a stock that collapses down without sacrificing reliability, this is a straightforward choice. It attaches directly to the receiver's Picatinny interface, deploys or folds in seconds, and keeps your overall footprint at 9 inches when collapsed—ideal for short-range work, vehicle carry, or tactical movement in tight spaces.

Build quality is typical Sig: anodized aluminum construction, minimal rattling, clean engagement. The buttpad measures 0.9 inches wide and sits 3.5 inches tall, delivering a slightly more compact profile than Sig's Minimalist Plus variant. It's not a premium precision stock and doesn't pretend to be; it's a working folder that does the job without unnecessary features or fuss.

Important: Folding and collapsible stocks are heavily regulated or prohibited in many states and jurisdictions. Some combinations with other firearm components may be illegal where you live. Federal, state, and local laws vary significantly. It is your sole responsibility to verify that this stock complies with all applicable laws and regulations in your area before purchase or use.
