The Strike Industries FSA Dual solves the directional folding problem by letting you fold left or right anytime without flipping components or reconfiguring the hinge – just choose your direction and fold. This brace works well for ambidextrous shooters, tactical situations requiring different folding directions based on cover, and anyone who wants maximum versatility from a single folding system. What sets the FSA Dual apart is the patented mechanism that’s truly bidirectional without compromise, plus the modular design lets you swap the stabilizer end for a stock end if you SBR the firearm, making it a long-term investment that adapts to your needs.
Note: Dirt and sand can hinder operation. Not recommended for mortaring firearm. Routine lubrication of hinge and button components required. Pressing both buttons simultaneously removes bar from hinge.
