Geissele Automatics Maritime Bolt Catch – AR-15/M4

The Geissele Maritime Bolt Catch is an oversized bolt catch designed for faster magazine changes and more positive bolt lock manipulation, especially when wearing gloves or in adverse conditions. The enlarged paddle extends beyond the lower receiver's profile, making it easier to activate the bolt release without adjusting your grip or fumbling for the standard-sized control. Developed for maritime and tactical environments where reliability under stress is non-negotiable, this bolt catch benefits any AR-15 operator who values speed and consistency during reloads.

Machined from mil-spec steel with a manganese phosphate finish for corrosion resistance and durability. Installation is straightforward and requires only basic armorer tools—no gunsmithing necessary. The Maritime Bolt Catch is a direct replacement for standard AR-15/M4 bolt catches and includes the roll pin for installation.
