They are still under our Limited Lifetime Warranty.
The Sylvan Arms Folding Stock Adapter allows you to fold your stock and significantly reduce the length of your rifle for easy stow and travel.
Specifically designed for gas piston and direct impingement systems .223 / 5.56 to .308 systems, it has standard 1-3/16” x 16 thread and does not require any additional parts to be used with standard Bolt Carrier Groups.

No special tools are required; only a standard armorer’s wrench. The product does not need to be disassembled in order to install it onto your rifle/pistol.
