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.
Machined from 6061 aluminum, the ALM is very sturdy, with cogged connections at each adjustment point. This ensures a very rigid, rattle-free connection at any position.

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. |
