Sylvan Arms AR Folding Stock Adapter Gen 3 5.56 308 Compatible

The Sylvan Arms ARH300 AR Folding Stock Adapter - Black Gen 3 from Sylvan Arms is precision CNC-machined in the USA from 7075 billet aluminum, delivering a lightweight 6.0-ounce solution that resists corrosion while maintaining rugged reliability for gas piston and direct impingement platforms. Specifically designed for 5.56 to .308 systems, and compatible with .223, it features a standard 1-3/16 x 16 thread and requires no additional parts to be used with standard BC Groups, so installation is quick and straightforward with only a standard armorer's wrench. The assembly folds and carries without altering the length of pull, and no disassembly is needed to mount it on your rifle or pistol. The hard coat black anodized finish complements a wide range of builds, while the hinge dimensions of 3 11/16 inches and a hinge weight of 6.0 oz (extension 2.2 oz; hinge length 1.3 inches) ensure a balanced profile. It also accommodates 9mm bolt carriers with a 5/8 inch ID by including a compatible bolt extension, with specific sizing options available for PSA or other carriers, though it does not work with Silent Capture Buffer Springs or JP Enterprise Buffer Systems. A limited lifetime warranty backs this versatile stock adapter designed, built, and assembled in the USA.
