A3 Sure-Lok 1913 Folding Hinge
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.
