Maxim Defense Sub Compact Weapon (SCW) Stock Gen 7 System - 5-Position Rapid Deploy Ultra-Compact PDW Architecture, Includes Proprietary SCW Bolt Carrier Group, Micro-Buffer & Recoil Spring Assembly, Fits Standard Mil-Spec AR-15 Lower Receivers, Anodized Matte Black Finish - MXM-47631 / 6800176476311
Product Description
Shaving every possible fraction of an inch off an AR-15 platform to create a true ultra-compact Sub Compact Weapon (SCW) or Personal Defense Weapon (PDW) requires an engineering overhaul of the rear buffer tracking assembly. Standard carbine receiver extensions add over 7 inches of length behind the lower receiver, while conventional short-buffer setups still protrude excessively and compromise bolt travel reliability on your bench. The **Maxim Defense® SCW Stock Gen 7 System (MXM-47631 / 6800176476311)** flatlines these sub-compact staging limitations, dropping total rear length to a micro **4.0 inches when collapsed** by pairing an ultra-short housing with its own proprietary SCW bolt carrier group.
Proudly engineered, CNC-milled, and torture-tested in the United States by Maxim Defense, the Gen 7 SCW system is carved from high-tensile **7075-T6 structural aircraft-grade aluminum alloy** finished in a non-reflective Type III hard-coat anodized matte black dressing. The core mechanical innovation is its shortened buffer housing and customized SCW bolt carrier group assembly, which allows the bolt to travel deeper into the upper receiver while maintaining 100% cyclic function. The stock features a **5-position rapid-deploy guide rod tracking system** that permits operators to instantaneously pull the stock rearward into full extension without depressing levers or buttons. Complete with dual anti-rotational QD sling swivel sockets, a micro-buffer, and a custom recoil spring, this turn-key conversion package turns your standard AR lower into a true micro-carbine straight from your armorer bench.
Engineered to thread directly into standard Mil-Spec AR-15 lower receiver extension threads, this factory-calibrated SCW system guarantees absolute structural and cyclic stability directly from your workspace bench.
*Armorer Bench Notes & Real-World Sub-Compact System Staging Guidance: The Maxim Defense MXM-47631 SCW Stock Gen 7 kit arrives workspace ready as a complete, self-contained PDW conversion system pack containing the 7075-T6 aluminum housing adapter, 5-position telescoping stock, proprietary SCW bolt carrier group (BCG), SCW micro-buffer, recoil spring, and mounting hardware. PROPRIETARY SCW BOLT CARRIER GROUP & RECEIVER MATRIX: The threaded extension housing is engineered natively to screw onto **standard Mil-Spec AR-15 / M4 lower receivers (1-3/16"-16 UN thread standard)**. *SCW Bolt Carrier Requirement Checklist:* Because the housing extension is shortened to an ultra-compact 4.0 inches, you **MUST use the included Maxim Defense SCW Bolt Carrier Group** provided in this kit—standard-length AR-15 bolt carriers will *not* clear the shortened housing buffer channel. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host AR-15 lower receiver is completely clear of live ammunition, the upper receiver is separated, and the lower cavity is safe and clear. 2. Remove your old receiver extension tube, castle nut, endplate, standard bolt carrier group, buffer, and recoil spring from the host firearm. 3. Ensure the rear takedown pin, detent, and detent spring are properly seated in the receiver. 4. Thread the Maxim SCW housing onto the receiver extension threads, ensuring the lower indexing tab captures the takedown pin detent spring flush. 5. Torque the housing assembly to **35 to 40 inch-pounds** using a proper armorer wrench on your bench. 6. Install the included SCW micro-buffer and spring into the housing, swap out your old BCG for the included Maxim SCW Bolt Carrier Group in your upper receiver, assemble the receivers, and cycle the charging handle manually several times to verify smooth bolt carrier travel before heading downrange.*
