Abstract
A gun which has an improved firing mechanism which enables it to be completely automatic through ejection of the magazine by eliminating the need for a selector switch. The firing mechanism has a substantially J-shaped hammer with a sear embedded therein. The sear is shaped, preferably hemispherically, at its framework end so that it will fall into a recess in the framework during the firing cycle. The draglink has a curved upper surface which is preferably concave or bowl-shaped. An associated magazine follower has a cam at its front center for tripping a release latch.

A firing mechanism and magazine release means for an automatic weapon, comprising:
- a straight pull trigger integral with a trigger guard and a forwardly extending arm,
- a draglink located in said arm,
- a rounded sear and hammer located above the forwardly extending arm, said sear being resilently mounted in the hammer,
- a frame structure having a rounded recess for seating and engaging a rounded portion of the hammer, and an opening therein for receiving the sear at a location over the forward arm of the trigger and adjacent the draglink when the hammer is located in a non-firing position,
- a receiver located above the trigger and hammer,
- a bolt positioned to travel through the receiver until it chambers a round,
- auto-trip means located adjacent the hammer and receiver for holding the hammer in a non-firing position when the magazine is empty and for releasing the same when the magazine contains one or more rounds and the trigger is pulled either to its most rearward position or to an intermediate position, and
