PFS-X Stock

The PFS-X Stock is a compact, performance-driven folding stock designed for modern 1913 Picatinny-mounted platforms. Built around the Sure-Lok™ Folding Hinge, it delivers a rigid, repeatable lock-up with fast, intuitive deployment, snapping solidly into the open position with a firm pull while allowing controlled folding via a dedicated push- button.

The PFS-X features a progressive cheek rest for improved optic alignment, a textured rubber buttpad for a secure shoulder interface, and a full-rotation QD sling socket that can be mounted on either side of the stock. Its low-profile, cross-bolt mounting system ensures a secure attachment without unnecessary bulk.

Available in Black, Flat Dark Earth, Olive Drab Green, and Grey, the PFS-X Stock delivers durability, modularity, and clean ergonomics in a streamlined package built for hard use.
