The Geissele Maritime Bolt Catch was specifically developed with the modern war fighter in mind. The bolt catch will work with any Mil-Spec lower receiver designed to accept a standard M16/M4 Carbine bolt catch. By increasing the surface area of the bolt catch it enhances the ability to manipulate the bolt catch especially under stressful conditions and during combat. As an added benefit the extended controls add functionality for left handed shooters who no longer have to break their grip in order to reach the bolt catch. The aggressive texturing enables positive feedback especially when using gloves or during night time operations. Made from heat treated 8620 steel and manganese phosphate coated the Geissele Maritime Bolt Catch will serve you well for years to come.
