Geissele Maritime Bolt Catch

The Geissele Maritime Bolt Catch is engineered with the needs of modern warfighters in mind. It is compatible with any lower receiver built to accept a mil-spec M16/M4 Carbine bolt catch. Featuring an enlarged surface area, it allows for easier operation when locking the bolt to the rear or releasing it during magazine changes. The extended controls offer improved accessibility for left-handed users, who can now operate the bolt catch without altering their grip—using the index finger of their dominant hand for quicker, more efficient manipulation. Additionally, aggressive checkering on the levers provides a textured surface for reliable tactile feedback, even when wearing gloves or operating in low-light conditions.
