Overview
The Sylvan Arms GCB100 is a 9mm magazine conversion block designed to adapt a standard mil-spec AR-15 lower receiver to accept Glock 17 and Glock 19 magazines. Constructed from 6061-T6 aluminum with an anodized black finish, this drop-in block allows for the use of 9mm AR-style uppers without the need for a dedicated pistol-caliber lower receiver. It includes a trigger-style magazine release for one-handed operation and is designed, built, and assembled in the USA.
