Sylvan Arms AR-15 Folding Stock Adapter Gen 4 Right Fold Black

The Sylvan Arms AR-15 Folding Stock Adapter Gen 4 Right Fold in Black is a lightweight, purpose-built receiver extension designed to convert standard AR rifle configurations into right-side folding setups. This adapter provides a compact storage solution without sacrificing functional stock performance when deployed. It is suitable for law enforcement tactical teams, military personnel, and civilian operators who prioritize compact rifle profiles.

The Gen 4 adapter features a right-fold geometry that positions the collapsed stock toward the firing side, maintaining natural grip access and reducing overall package depth for vehicle operations and confined-space navigation. Weighing only 0.64 lbs, it adds minimal mass to the rifle platform while ensuring structural rigidity for consistent cheek-weld geometry when the stock is extended. The design is compatible with standard mil-spec AR buffer tubes and accepts a variety of folding stocks.

This adapter is ideal for users looking for reliable stock positioning under recoil, making it a valuable addition for repeated field deployments. The Gen 4 iteration reflects refinements in hinge durability and positive locking engagement. Its black anodized finish resists corrosion and maintains a consistent appearance with most modern AR builds.
