PFS-X | 1913 Mount Folding 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.

Features

Sure-Lok 1913 Folding Hinge - Patent Pending
The Sure-Lok™ Folding Hinge features 17-4 stainless steel MIM construction with a QPQ finish for strength, wear resistance, and corrosion protection. A push-button release allows controlled folding, while the quick-deploy design lets the stock snap into the deployed position with a firm pull, no extra steps required. Its compact, low-profile design mounts securely to any 1913 Picatinny rail using two cross-bolts for maximum rigidity, or a single centered cross-bolt when space is limited, delivering fast operation, durability, and repeatable performance.

Progressive Cheek Rest
The progressive cheek rest is manufactured from injection-molded, fiber-reinforced polymer for a lightweight yet durable profile. Its upward-slanting geometry provides a natural ¼" to ½" of cheek rise, improving head position and eye alignment across a wide range of optics. The tapered design allows shooters to find a consistent cheek weld without abrupt height changes, and the cheek rest can be removed entirely for use with low-mounted optics or minimalist configurations.

Rubber Buttpad
The rubber buttpad features an aggressive, high-traction texture designed to keep the stock planted during recoil and rapid movement. Molded from durable rubber for long-term resilience, it provides a secure shoulder interface without snagging gear or clothing. A raised A3 logo is integrated into the texture, adding subtle branding without compromising grip or function.

Full Rotation Steel QD Socket
The full-rotation QD socket is constructed from machined, hardened steel to withstand repeated sling attachment and dynamic loading without wear. Designed for versatility, it can be mounted on either the left or right side of the stock, allowing users to configure their sling setup to match their shooting style. The hardened steel interface ensures smooth rotation and long-term durability under hard use.
