Geissele Super Stainless Magazine Catch Features The Super Stainless Magazine Catch is machined from stainless steel specifically for its anti-rust properties and extended service life providing a corrosion-resistant magazine catch solution for shooters who demand long-term reliability from every component in their AR-platform rifle. Drop-in compatibility with standard AR-platform lower receivers keeps installation straightforward without modification fitting or specialized armorer tools beyond a standard AR armorer s block. The complete assembly includes a magazine release spring delivering everything needed for a full factory-spec replacement in a single package. As a stainless steel AR magazine catch the SSMC provides a stronger foundation than mil-spec carbon steel catches that are susceptible to surface rust and wear in high-humidity environments hard use and extended storage. The Geissele design maintains the same dimensional profile as the mil-spec component for seamless integration with standard lower receivers and magazine well geometry. For shooters who run their rifle hard or store it in demanding conditions the SSMC is a straightforward upgrade that adds meaningful longevity without altering the manual of arms.
