MDT SCS Skeleton Carbine Stock Kit Matte Black Fits MDT Carbine Stock Interface 102856 BLK UPC 990482719968
Product Description
The MDT® SCS Skeleton Carbine Stock Kit (SKU: 102856-BLK / UPC: 990482719968) delivers maximum structural rigidity and toolless ergonomic adjustability for bolt-action chassis rifles utilizing the MDT Carbine Stock Interface. Engineered for precision rifle competition, long-range hunting, and tactical applications, the SCS bridges the gap between compact carbine interfaces and full-featured precision buttstocks.
CNC-machined from solid 6061-T6 aircraft-grade aluminum, the SCS features a durable matte black Cerakote finish paired with hard-anodized aluminum buffer tube and cheek riser posts for smooth, bind-free operation. Its rigid skeletonized chassis architecture eliminates flex under heavy magnum recoil while maintaining an overall adjustable length range of 9.85 to 10.85 inches.
Designed for rapid positional adaptability, the SCS provides toolless adjustment for Length of Pull (LOP) and cheek riser elevation so shooters can establish a consistent, repeatable cheek weld behind high-magnification optics. Integrated ambidextrous QD sling attachment points and a bottom M-LOK slot allow direct mounting of bag riders, monopods, and tactical sling hardware.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Fits MDT chassis systems built with the MDT Carbine Stock Interface (1-3/16"-16 UN threads), including MDT LSS and LSS-XL Gen 2 Carbine models. CRITICAL WARNING: The SCS ships as a complete integrated assembly with its own anodized buffer tube and will NOT mount over existing Mil-Spec (1.148") or Commercial (1.168") receiver extensions. It will NOT fit MDT Fixed Stock Interfaces or MDT XTN interfaces (ACC/ESS) without an adapter. On bolt-action chassis platforms, torque the receiver extension castle nut to 38–40 ft-lbs; if adapting to a semi-automatic AR-pattern lower, verify proper buffer/spring compatibility and stake the castle nut notch.
- Ensure the host firearm is completely clear, magazine removed, and chamber visually and physically verified empty before beginning installation.
- Remove any existing receiver extension and inspect the chassis rear 1-3/16"-16 UN carbine interface threads for debris or old threadlocker.
- Thread the MDT SCS integrated buffer tube assembly into the chassis interface until properly indexed and aligned vertically with the receiver bore axis.
- Tighten the locking castle nut firmly against the chassis rear plate using a calibrated armorer wrench to 38–40 ft-lbs.
- Adjust Length of Pull (9.85"–10.85") and cheek riser height to match your optic eye relief, verify bolt throw clearance, and confirm rock-solid lockup before live-fire zeroing.
