Maxim Defense CQB Buttstock Assembly Only - Replacement Stock Endpiece Unit, Dual Steel Guide Rods, Polymer Cheek Rest & Buttplate, Fits Maxim Gen 6 CQB Housing & PDW Brace Systems, Anodized Black Finish - MXM-47575 / 680017475758
Product Description
Converting a Maxim Defense CQB pistol brace assembly over to a SBR rifle setup, replacing a damaged guide rod endpiece, or staging a modular PDW build requires factory-original replacement assemblies built to exact mechanical prints. Attempting to fit aftermarket stock parts onto proprietary housing rails can lead to binding along the guide channels or loose locking engagement on your bench. The **Maxim Defense® CQB Buttstock Assembly Only (MXM-47575 / 680017475758)** flatlines these conversion bottlenecks, delivering a **turn-key factory replacement stock module** designed specifically to interface with existing Maxim Gen 6 CQB housings and brace assemblies.
Proudly engineered and CNC-machined in the United States by Maxim Defense, this replacement buttstock assembly consists of high-strength **dual steel guide rods**, a durable polymer cheek rest block, and a steel-reinforced textured buttplate. Finished in a matching non-reflective matte black dressing, this module allows owners of Maxim Gen 6 CQB Pistol Braces or PDW Brace systems to swap out their pistol arm cuff for a full shoulder buttstock (NFA rules apply). The assembly slides directly into the guide channels of your existing Maxim Gen 6 housing, restoring or expanding your platform's operational capabilities straight from your armorer bench.
Engineered to slide seamlessly into Maxim Defense Gen 6 CQB housing extension rails, this factory-calibrated stock unit guarantees absolute mechanical fitment directly from your workspace bench.
*Armorer Bench Notes & Real-World Stock Module Conversion Guidance: The Maxim Defense MXM-47575 stock module arrives workspace ready as a pre-assembled replacement unit featuring dual steel guide rods, integrated cheek rest housing, and buttplate. PROPRIETARY MAXIM DEFENSE SYSTEM COMPONENT MATRIX: This replacement component is engineered natively, strictly, and dimensionally to slide into **Maxim Defense Gen 6 CQB Housing Adapters and Gen 6 PDW Pistol Brace system rails**. *System Conversion & Legal Compliance Checklist:* This package includes the **buttstock assembly only**—it does *not* include the housing adapter, buffer tube, buffer, or recoil spring. Converting a pistol platform equipped with a brace over to this shoulder buttstock creates a Short-Barreled Rifle (SBR); ensure all NFA registration requirements and local legal regulations are fulfilled on your bench prior to installation. Armorer Workbench Custom Staging Sequence: 1. Visually and physically confirm your host firearm is completely clear of live ammunition, the magazine is removed, and the receiver cavity is safe and empty. 2. Depress the central locking release lever on your existing Maxim Gen 6 housing adapter to disengage the guide rods. 3. Pull your current brace cuff or stock assembly completely rearward and out of the housing guide tracking channels. 4. Clean and apply a micro-drop of high-grade lubricant along the twin steel guide rods of the new MXM-47575 stock assembly. 5. Guide the new stock rods straight into the lateral housing tracks until the internal locking mechanism engages the first indexing notch. 6. Cycle the stock through all length-of-pull positions to verify smooth sliding travel and crisp lockup before rolling downrange.*
