The Sylvan Arms Gen 3 AR-15 Folding Stock Adapter is compatible with 5.56 and .308 pattern rifles and allows you to fold your stock for a more compact package for storage. It simply screws into the receiver extension slot where your buffer tube would and then you screw your buffer tube into the stock adapter. The gen 3 folding stock adapter is CNC machined from 7075-T6 aluminum with a heavy duty hinge and hardcoat anodized black for long term corrosion resistance.

Note: Do not fire when open.
