SYLVAN ARMS AR-15 9mm Glock Magazine Conversion Block, Steel/6061-T6 Aluminum, Black Anodized GCB100

Product Description

The SYLVAN ARMS GCB100 9mm Glock Conversion Block is a drop-in magwell adapter designed to convert a standard Mil-Spec AR-15 lower receiver for use with 9mm Glock-pattern magazines. It installs much like a standard rifle magazine for quick setup and easy swap-out, helping you build or convert a pistol-caliber carbine without purchasing a dedicated 9mm lower. Constructed from steel and 6061-T6 aluminum with a black anodized finish, it is built for durability and reliable fitment. This conversion block does not include a last round bolt hold open feature.
