Synthetic rubber gasket fits between the trigger group and the lower receiver to prevent blown primers and other debris from wedging under the trigger and causing malfunctions. Gives service rifle and three gun competitors, military, and law enforcement shooters extra insurance that a simple problem won't render a rifle unusable. Installation requires removal of safety selector, hammer, and trigger assembly; gunsmith installation recommended. May cause small increase to trigger pull.
