Sig Sauer MCX MPX FDE Telescoping and Folding Stock Fits Sig MCX MPX 1913 Interface Flat Dark Earth STOCK X FOLD TELE FDE UPC 798681544011
Product Description
The Sig Sauer Telescoping and Folding Stock in Flat Dark Earth (STOCK-X-FOLD-TELE-FDE) is a factory original equipment modular stock assembly engineered specifically for Sig Sauer MCX, MCX Spear, MCX Rattler, and MPX platforms, as well as firearms equipped with a rear MIL-STD-1913 Picatinny stock rail interface. Combining side-folding versatility with multi-position length-of-pull adjustments, this factory stock provides custom shoulder ergonomics and compact transport capabilities.
Constructed from high-strength polymer and reinforced steel/aluminum hinge components, the STOCK-X-FOLD-TELE-FDE features a 5-position telescoping cheek weld housing that allows shooters to quickly tune length-of-pull for body armor, tactical vests, or varied shooting stances. The heavy-duty steel hinge assembly folds securely to the left side of the receiver, significantly reducing the overall footprint of the firearm for vehicle staging and covert bag transport.
Featuring integrated push-button QD sling attachment sockets on both sides and a rubberized buttpad to prevent shoulder slippage, this genuine Sig Sauer factory stock installs effortlessly in seconds via a single 1913 Torx clamping mechanism.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Direct fitment for Sig Sauer MCX, MCX Virtus, MCX Spear-LT, MCX Rattler, and MPX series. Compatible with any rifle, carbine, or NFA SBR equipped with a rear vertical MIL-STD-1913 Picatinny stock rail adapter. (All NFA laws apply when installing on pistol-configured firearms).
- Perform a complete firearm safety check: drop the magazine, lock the bolt/charging handle rearward, and visually inspect the chamber to verify zero live rounds are present.
- Loosen the cross-bolt clamp on the stock's 1913 hinge mount using the appropriate Torx key.
- Slide the 1913 hinge interface onto the rear vertical Picatinny rail of the receiver, aligning it with the desired height slot.
- Torque the mounting clamp screw to 25–30 in-lbs to guarantee zero movement under heavy recoil.
- Depress the hinge release button to verify positive folding and lockup against the side of the receiver, then extend to check lockup in the firing position.
- Depress the length-of-pull adjustment lever to cycle through all 5 telescoping positions and select your preferred setting.
