The JRC Heavy Weight Magwell — compatible with GLOCK pistols — is precision-machined from carbon steel and finished in either Armor Black Cerakote or FDE Cerakote. The magwell and weight plug are not brass; the magwell body is carbon steel and the included weight plug is stainless steel. The plug adds weight to the complete assembly, bringing the total assembly weight to approximately 9.4 oz.
