Geissele Automatics

The Geissele Maritime Bolt Catch is engineered for the warfighter and functions with any lower receiver designed to accept a mil-spec M16/M4 Carbine bolt catch. Increased surface area on the control levers improves ease of operation when locking back the bolt or releasing it after a magazine change. The extended controls provide enhanced functionality for left-handed shooters, who can now manipulate the bolt catch using their left index finger without breaking grip—making magazine changes and bolt lock-back operations faster and more efficient. Aggressive checkering on the lever surfaces creates a textured finish that delivers reliable tactile feedback when operating with gloves or in low-light conditions. Machined from heat-treated 8620 steel and finished with manganese phosphate coating, the Geissele Maritime Bolt Catch serves as an enhanced mil-spec replacement designed to provide overmatch capability on the M16/M4 carbine platform.
