The Strike Industries Dual Folding Stock Adapter is a 1913 Picatinny folding adapter built to fold either left or right without reconfiguring the platform (brand part no. SI-FSA-DUAL-STOCK). Strike Industries machines it from 6061-T6 aluminum and adds a patented locking mechanism with built-in locking lugs for a positive lock in the folded position. Its interchangeable design lets the same adapter swap between a stabilizer end and a stock end, which is where the “Dual” name comes from. Compatible with most 1913 Picatinny rear interfaces, including factory OEM Picatinny-equipped firearms, it’s a versatile way to add a fold-flat option to nearly any Picatinny-braced build.
