Patent ID: 8899141

Claim:
A method of reducing the cyclic rate of a self-powered firearm, comprising: allowing a timing group assembly to travel rearward relative to a pull rod within a receiver extension of a self-powered firearm upon an initial recoil action; retaining an inertia weight of the timing group assembly at a rearward position within the receiver extension while disengaging the inertia weight from the remainder of the timing group; urging the remainder of the timing group to travel forward relative to the pull rod; advancing the pull rod to disengage the inertia weight from the rearward end of the receiver extension; urging the disengaged inertia weight to travel forward within the receiver extension; and, allowing the inertia weight to travel forward to an impact position wherein said inertia weight communicates force forward sufficient to actuate a sear to fire the firearm.
