Patent attributes
An ambidextrous lower receiver for an automatic rifle is an apparatus that allows a rifle bolt of an upper receiver that is mounted on the apparatus to be manipulated from either side of the automatic rifle. The apparatus includes a lower-receiver body, a bolt catch button, a bolt catch lever, a pusher finger, and a length-adjustable pin. The lower-receiver body attaches with the upper receiver of an automatic rifle and connects a magazine and a pistol grip to the automatic rifle. The lower-receiver body positions the bolt catch button and the bolt catch lever. The bolt catch button releases and locks the bolt catch lever. The bolt catch lever releases and locks the rifle bolt of a corresponding upper receiver. The bolt catch button manipulates the bolt catch lever from the opposite side of the automatic rifle with the pusher finger and the length-adjustable pin.
