ALM – ADJUSTABLE LENGTH MODULAR FOLDING STOCKS – PICATINNY (1913)

Product Description

The ALM Adjustable Length Modular Folding Stocks are packed full of features. Available in straight or offset configurations, both variants have 5 length settings, a cheek riser with adjustable height and adjustable mounting positions, and a Quick-disconnect (QD) sling mounting socket – all standard when you buy the ALM folding brace.

Extension arms: Choice of straight or offset extension arms.
Mounting interface: 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.
Cheek Riser: XENO modular cheek riser included. 3-height adjustments via cheek riser pad and 1/4″ spacers. Heights of 7/8″, 1-1/8″, and 1-3/8″ to work with just about any optic height. Can mount riser to either side of extension arm, in 3 different horizontal mounting positions.
4 butt-plate options available: We have multiple butt-plate options for various requirements. Our A3T model is perfect for a more compact scenario. The Magpul 1 Magpul 2 are both larger butt-plates and feature steel QD sockets and standard sling loops. The Xtendo narrow butt-plate works for applications that need more clearance when folded. They also extend the stock an additional 2″ in length.
VIS Quick-disconnect (QD) socket: An optional steel QD socket is available if needed. These can mount to any of the adjustment holes on the side of the extension.
