Sylvan Arms Conversion Block AR-15 to 9mm Luger P320, Black - SYL SCB100

This drop-in conversion block transforms a standard AR-15 lower receiver into a 9mm P320-compatible platform without requiring a dedicated pistol-caliber lower. It installs seamlessly into Mil-Spec AR-15 receivers and enables shooters to use 9mm ammunition while maintaining full AR-15 functionality. California Proposition 65 warning applies.
