Abstract
Certain embodiments disclose rate reducer systems and methods to reduce the cyclic rate of self-powered firearms. The reduction in cyclic rate is achieved by mechanically delaying the firing step in the cycle of functioning. This delay is achieved by temporarily latching an inertia weight at the rear of the recoil stroke while the recoiling parts return to battery (i.e. a firing position). When the recoiling parts go into battery, the inertia weight is released and urged forward. At the forward end of its travel, the inertia weight actuates the firing mechanism.
Claims20
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.
A cyclic rate reduction assembly for a self-powered firearm, comprising:
- a timing group having an inertia weight arranged within a receiver extension of a self-powered firearm;
- a pull rod arranged within the receiver extension, wherein said timing group can selectively translate rearward relative to said pull rod during a recoil stage of the firearm;
- a weight latch mechanism to retain said inertia weight of said timing group at a rearward position within the receiver extension while disengaging the inertia weight from the remainder of the timing group;
- a drive biasing element urging the remainder of said timing group to travel forward relative to the pull rod at the end of the recoil stage;
- wherein said timing group impacts a forward end of the pull rod during said forward movement causing said pull rod to move forward;
- wherein said pull rod includes a rear portion which causes said weight latch mechanism to disengage said inertia weight from the rearward end of the receiver extension when said pull rod moves forward;
- and,
- a weight biasing element urging said disengaged inertia weight to move forward to an impact position to communicate force forward to actuate a sear to fire the firearm.
A self-powered firearm incorporating a cyclic rate reduction assembly, comprising:
- a self-powered firearm having a receiver extension and having a sear element which can be tripped to fire the firearm during automatic fire;
- a timing group initially arranged within a forward portion of said receiver extension and having an inertia weight, wherein said timing group can translate rearwardly against a drive biasing element during a recoil stage of the firearm;
- a pull rod arranged within said receiver extension,
- a latch mechanism arranged to retain said inertia weight at a rearward position within the receiver extension while disengaging the inertia weight from the remainder of the timing group and wherein said biasing element urges the remainder of said timing group to translate forward without said inertia weight;
- wherein said timing group impacts a forward end of the pull rod during said forward movement whereupon the pull rod translates force to a rear portion which disengages said latch mechanism;
- and,
- a weight biasing element urging said inertia weight to move forward sufficiently to communicate force forward to trip said sear.
