ABSTRACT:
A firing mechanism for a weapon having a receiver with a chamber for a caidge comprises a bolt and piston which are separately movable toward and away from the chamber and which are engaged with each other for displacing and rotating the bolt into a locked firing position. A buffer is also movable in the receiver and can strike the rear end of the piston. The piston carries a firing pin which can thus be driven into the primer of a cartridge in the chamber. Three sears are provided. Two of the sears are for engaging the piston, one sear for holding the piston in a position with its firing pin away from the cartridge but with the bolt against the chamber and in its locked position. The other sear for the piston holds the piston with the bolt in a position away from the chamber. This is for open bolt operation. A third sear is provided for engaging the buffer for closed bolt operation. A fire selector is provided which can act as a safety and which provides an automatic and a semi-automatic position for stopping rotation of the sears at appropriate positions for automatic or semi-automatic fire.
