Abstract
A recoil-operated, impulse averaging, air-cooled, magazine-fed, automatic weapon. An operating group of the weapon includes a chamber, a bolt, a barrel extension and one or more toggles. The recoil action of the weapon from firing a first round drives the toggles in a motion constrained by a cam way. The toggles then drive the chamber in a linear reciprocating motion ejecting a first round and over-riding the next round. An impulse averaging system controls the speed of the recoil.

A recoil operated firearm comprising:
- a receiver;
- a barrel having a longitudinal axis;
- a bolt spaced a distance from a rearward end of the barrel along the longitudinal axis of the barrel;
- a barrel extension attached to the bolt and connecting the barrel with the bolt, the barrel extension and bolt adapted to move linearly with respect to the receiver in a direction parallel to the longitudinal axis of the barrel;
- a chamber movable relative to the bolt between an ammunition loading position and a firing position;
- and
- a toggle adapted to drive the chamber between the loading position and the firing position in response to movement of the barrel extension and bolt relative to the receiver.
