XTS 1913 Folding Buffer Tube Adaptor 1913 Picatinny Rail to AR Buffer Tube 7075 Aluminum Construction Black XTS 1913FLDA UPC 767820118796
Product Description
The XTS 1913 Folding Buffer Tube Adapter (MPN: XTS-1913FLDA) is a rugged side-folding stock adapter designed to attach standard AR-15 carbine buffer tubes and receiver extension stocks onto firearms equipped with a rear 1913 Picatinny rail interface. Precision CNC-machined from ultra-durable 7075-T6 aircraft-grade aluminum, this side-folding hinge module drastically minimizes the overall footprint of non-AR bufferless rifles and pistol-caliber carbines for discreet vehicle transport, backpack storage, and tight-quarters staging.
Featuring a hardcoat anodized matte black protective finish, the XTS-1913FLDA utilizes a heavy-duty positive lockup hinge mechanism that locks securely in both extended and folded positions, eliminating unwanted wobble or play under hard shoulder force. The rear female threading accepts all standard Mil-Spec or Commercial-spec AR-15 buffer tubes, enabling shooters to mount their preferred collapsible carbine buttstocks or stabilizing pistol braces to bufferless weapon chassis.
Engineered with dual heavy-duty steel clamping screws, the XTS-1913FLDA mounts seamlessly onto any standard rear MIL-STD-1913 Picatinny rail section (such as SIG MCX/MPX, CZ Scorpion, Ruger LC Carbine, or BRN-180 builds) without requiring permanent weapon modification. Backed by XTS quality assurance, it provides smooth, intuitive push-to-fold deployment for modern tactical firearms.
Armorer Bench Notes & Real-World Staging Guidance:
Fitment Matrix: Mounts directly to any rear vertical 1913 Picatinny rail endplate (SIG SAUER MCX/MPX, Ruger LC Carbine/PC Charger, CZ Scorpion EVO with 1913 endplate, AK 1913 stock adapters, B&T, and BRN-180 bufferless lower receivers). Accepts all standard 1-3/16"-16 tpi AR-15 carbine buffer tubes (Mil-Spec or Commercial). (Note: Designed strictly for BUFFERLESS firearm operating systems that do not require an active buffer and spring inside the extension tube to cycle; attempting to fire a standard AR-15 gas-impingement system while folded will cause catastrophic receiver failure).
- Perform a complete firearm safety check: drop the magazine, lock the bolt rearward, and visually inspect the chamber to verify zero live rounds are present.
- Loosen the side clamping screws on the XTS-1913FLDA adapter using an Allen wrench.
- Slide the clamp interface downward over the rear vertical 1913 Picatinny rail section of your firearm until properly seated in the desired rail slot.
- Torque the side clamping screws evenly to manufacturer specification (25–30 in-lbs) to lock the hinge housing securely to the rail.
- Thread your AR-15 buffer tube into the female rear threads of the folding hinge housing until hand-tight, align the buffer tube timing channel vertically, and secure with a standard castle nut and endplate if applicable.
- Depress or lift the hinge mechanism to test smooth side-folding operation and verify rock-solid lockup in both folded and deployed positions before shoulder staging.
