Fortis Manufacturing Billet Magazine Catch and Release Features The Fortis Manufacturing Billet Magazine Catch and Release is machined from a solid piece of 6061-T6 aircraft grade aluminum giving it a level of fit and finish beyond the typical stamped mil-spec component. Its low profile design matches the footprint of a standard mil-spec magazine button which helps prevent the catch from being over-thrown during a fast reload. Aggressive front serrations are cut into the button face to improve grip and control when releasing a magazine under time pressure or with gloved hands. A Nitride finish in Olive Drab Green adds corrosion resistance while giving the part a distinct look that stands out from a plain black lower. Full length threaded internals run the depth of the part paired with a magazine rod machined from 303 stainless steel for additional long term durability over a standard steel rod. An engraved logo and added surface texture round out the design giving the catch both function and a touch of styling. Because it is a direct drop in replacement for the component found in a standard AR-15 lower parts kit installation takes only seconds with no special tools or gunsmithing required. For AR-15 owners looking to refine the feel and durability of their lower build this billet magazine catch and release is a quick worthwhile upgrade.
