Quantity in Stock: Strike Industries Dual Folding Adapter Stabilizer - SI-FSA-DUAL-STAB
The Strike Industries Dual Folding Adapter Stabilizer gives pistol-platform builders a highly modular rear-end solution built around a true dual-direction folding design. Made for platforms with a rear 1913 Picatinny rail interface, this stabilizer-equipped adapter can be folded to either the left or right side without needing to flip, reconfigure, or reinstall the hinge assembly. That means more flexibility for storage, transport, and platform setup without sacrificing fast deployment.
This exact model, SKU: SI-FSA-DUAL-STAB, is the stabilizer version of Strike’s Dual Folding Adapter system. It ships fully assembled with the stabilizer end installed, making it a strong option for builders looking for a compact, feature-rich folding rear assembly for compatible pistols and other 1913-railed firearm platforms. Strike also designed the system with a positive lock when folded, an intuitive rapid-deployment mechanism, and a 3-degree downward tilt intended to help reduce interference with the ejection port when folded to the right side.
Construction combines a steel hinge with a 6061-T6 aluminum base, adapter, and strut to balance strength and weight, keeping the unit at 9.60 oz. The adapter mounts directly to a 1913 interface using two built-in locking lugs for a secure fit, and a rear QD sling mounting point is integrated into the setup. Strike also includes rubber pads of varying thicknesses so the user can fine-tune the locking tension when the unit is fully deployed.{index=3}
For builders working with compatible chassis, lowers, and rear rail systems, the SI-FSA-DUAL-STAB offers a compact footprint, quick handling, and true left-or-right folding capability in one modular package. It is compatible with rear-facing 1913 Picatinny rails and is listed by Strike for use with platforms such as the BRN-180 lower, CZ Bren 2, Galil ACE, Ruger PC Charger, SIG MCX/MPX, and other setups using a proper rear Picatinny mounting interface.
