MDT SRS XF Premier Folding Stock Fits MDT XTN Stock Interface Black 114484 BLK UPC 990482710491
Product Description
The MDT® SRS-XF Premier Folding Buttstock in Black (SKU: 114484-BLK / UPC: 990482710491) provides an uncompromising, rock-solid platform for PRS/NRL competitive shooters, tactical operators, and long-range precision riflemen. Purpose-built to mount directly to MDT chassis systems featuring the proprietary XTN (External Threaded Nut) interface, this skeletonized folding stock slashes rifle footprint for pack carry, vehicular staging, and tight storage while locking up with absolute, zero-slop mechanical rigidity upon deployment.
Precision-machined from solid billet 6061-T6 aerospace aluminum, the SRS-XF Premier features an aggressively skeletonized frame that sheds excess weight while maintaining structural resistance to torsional twist. The exterior is coated in a durable Cerakote Black finish that defends against harsh bore cleaners, environmental moisture, and abrasive range grit. The internal locking mechanism uses hardened contact surfaces and a robust push-button release to guarantee zero hinge deflection or zero shift under repeated, high-cadence magnum recoil.
Tailored ergonomic adjustment is integrated throughout the chassis extension. A streamlined, low-profile cheek riser offers 1.20 inches of vertical travel and 0.60 inches of fore and aft movement to align your eye with high-magnification precision optics, all while providing a deep clearance pocket for unobstructed bolt extraction and rod guide clearance. Length of pull (LOP) is fine-tuned from 12.50 to 13.50 inches using four included stackable 1/4-inch spacers, complemented by an adjustable recoil pad with vertical and cant positioning, integrated QD sling swivel cups, and an underside M-LOK mounting slot for bag riders or balance weights.
*Armorer Bench Notes & Real-World Staging Guidance:*
Fitment Matrix: Exclusively compatible with MDT chassis featuring the proprietary XTN (External Threaded Nut) stock interface, including ACC Premier Gen 2, ACC Elite XTN, ESS, TAC21 Gen 2, and LSS Gen 3 with XTN adapters. CRITICAL: Not compatible with standard AR-15 / M4 carbine buffer tubes or standard A2 fixed buffer tubes. Reversible hinge design allows folding to the left or right; on left-handed actions or Ruger American chassis setups, configure the folding adapter orientation to fold away from the bolt handle to prevent binding. Secure the central 7/32-inch interface mounting bolt using medium-strength blue threadlocker (Loctite 242 / Vibra-Tite 121) torqued to 55-60 in-lbs into the chassis receiver block. Torque cheek riser locking set screws to 15-18 in-lbs to prevent slippage under sustained magnum recoil.
- Ensure the host rifle is completely unloaded, the magazine is removed, and the chamber and magazine well are visually and physically verified clear.
- Separate the SRS-XF Premier folding stock adapter from the skeletonized body if required, or open the folding hinge to access the central 7/32-inch mounting fastener cavity.
- Index the stock's front XTN alignment lugs precisely into the chassis receiver interface, ensuring square alignment against the chassis rear profile.
- Thread the primary mounting bolt through the stock hinge mechanism into the chassis threads, apply blue threadlocker, and torque to 55-60 in-lbs using the included 7/32-inch T-handle hex wrench.
- Adjust cheek rest height, cheek cant, and LOP spacers using the provided hardware to establish proper optic eye relief, then verify smooth bolt travel clearance throughout the full throw.
Key Features
