Magazine and bolt release for firearm

Abstract

An integrated magazine and bolt release mechanism that is intended to automate the operations of magazine release when empty, and bolt release when a loaded magazine is inserted into the rifle. The release mechanism may include a mechanical switch device. The mechanical switch device may be a lever that is able to identify the presence of ammunition. By way of mechanical linkage, the system is able to control the magazine catch surface to either maintain or expel a magazine. The linkage facilitate the transition of vertical motion, imparted by the magazine body and follower to the lever into horizontal motion of an arm to move the magazine catch in and out of engagement with the magazine's locking surface. Upward vertical motion of the lever may actuate the bolt catch surface by means of a mechanical link that serves to reverse the direction of vertical motion. As the magazine body moves upward, the lever impinges on the arm that forces the bolt catch downward, to release the locked bolt group.
