793811767131 STRIKE FSA SINGLE FOLDER STOCK EDITION The Stock Single Folder still utilizes the same arm and stock end piece as SI’s Dual Folder it has a strengthened hinge made of steel, instead of aluminum, making it extremely robust. The fitment is also perfect with little to no play when extended and folded. This folder only folds to a single side but can do so at any time without reconfiguring or using a button. When the hinge is installed to fold left, users will experience similar muscle memory if they've already used their Dual Folder - the action is the same to fold. Simply lift up on the arm and fold to the left. In its folded position, the arm can be forcefully thrown back into the extended position for quick deployment with no risk of damage to the hinge thanks to its new beefed-up design. At the 3 and 9 o'clock positions there are two QD points located on the stock end piece for attaching your favorite sling. The Strike Single Folding Adapter is compatible with any weapon platform that has a rear-facing 1913 Picatinny rail. To attach, tighten the hex screw in the hinge adapter onto a pic rail.
