Strike Industries FSA Dual Folder Stabilizer (1913)

The Strike Industries FSA Dual Folder Stabilizer is the brace variant of the FSA Dual Folder Stock. Same true bidirectional steel hinge that folds left or right without disassembly, same 6061-T6 aluminum body, same universal 1913 mount; the only change is a soft brace cuff in place of the rifle buttplate, which keeps it pistol-legal.

Construction is steel hinge with 6061-T6 aluminum base, adapter, and strut. Total weight is 9.9 ounces. Adds 9.18 inches when extended and 1.02 inches when folded. A 3-degree downward tilt prevents interference with the ejection port when folded right. Rubber pads at the folding adapter let you adjust the lock tension. Ambidextrous QD sling sockets and a rubber anti-slip cuff round out the build.

Mount on any 1913 Picatinny rear interface. The Dual Folder Stab is the only universal 1913 brace currently shipping with a true bidirectional hinge, which is the answer for left-handed shooters and for hosts where ejection-port clearance matters in both fold directions. Trade-off is roughly $20 more than the SI FSA Single Folder Stab and a heavier weight than the polymer FS1913.
