Strike Industries FSA Dual Folding Adapter – Stabilizer Edition (SI-FSA-DUAL-STAB)

The Strike Industries FSA Dual Folding Adapter, Stabilizer Edition, is a patented folding brace for firearms with a rear 1913 Picatinny mount. It folds to the left or the right, and you don't have to flip or reconfigure the hinge to change sides. It locks positively in the folded position. To deploy it, pull up and back on the bar near the hinge. A 3° downward tilt keeps the folded adapter clear of the ejection port when it is folded to the right. It weighs 9.6 oz and ships assembled with the stabilizer end. Strike part number SI-FSA-DUAL-STAB.
