The MDT V5 Skeleton Rifle Stock in FDE is a precision buttstock purpose-built for bolt-action rifle chassis systems, delivering the adjustability and lightweight construction competitive shooters and long-range hunters demand. Machined from 6061-T6 aluminum and finished in durable Cerakote, this modular stock eliminates the need for gunsmithing or tools when fine-tuning your shooting position—large thumbwheels let you dial in length of pull and cheek-riser height on the fly to match your natural shooting posture and optic setup.
Designed primarily for the TAC21 chassis but also compatible with LSS-XL, LSS, and HS3 systems, the V5 gives you the flexibility to optimize comfort and repeatability across different rifle platforms. The integrated bolt cut-out in the cheek rest means you can remove your bolt without breaking down the stock, a small feature that saves real time between rounds. Angular cheek-rest adjustment of up to 8 degrees on either side accommodates various shooting styles and body mechanics, while M-LOK slots accept 1.5" rails and other standard accessories for sling mounts or additional gear. Two QD flush cup sling attachment points on either side keep your setup clean and snag-free. The stock ships with a mini buffer tube for direct installation—note that it does not accept standard AR-pattern buffer tubes, so verify compatibility with your chassis before ordering.
If you're running a bolt-action precision rifle and tired of shimming, taping, or permanent modifications to get the fit right, the MDT V5 offers the kind of tunable ergonomics that cut down on shooting fatigue during long range sessions and competition days. The FDE finish blends into most field rifles and integrates seamlessly with modern tactical builds.
