The Sylvan Arms Folding Stock Adapter lets you fold your stock to drastically shorten your rifle for easy storage and transport. The Gen 4 AR Folding Adapter is designed to sit closer to the lower receiver, reducing overall length and eliminating gaps, making your AR more compact. It works with most AR-15s, as well as some AR-9s and AR-10s (note: some AR-9 BCGs may not be compatible). Featuring a standard 1-3/16” x 16 thread, it doesn't require additional parts for use with standard AR-15 Bolt Carrier Groups. It’s also compatible with JP Enterprises' Silent Capture Buffer Spring straight out of the box. CNC-machined in the USA from 7075 billet aluminum, this lightweight and corrosion-resistant assembly weighs just 6 ounces. A wrench is included for quick and easy installation, and no disassembly is required to attach it to your rifle or pistol.
