Ambidextrous integrated bolt and magazine release system for firearms

Abstract

A control system for a firearm platform includes a chassis, a first bolt actuator rotatably received within the chassis having an upward position and a downward position and configured to engage a bolt when in the upward position. A second bolt actuator is rotatably received within the chassis and operatively engaged with the first bolt actuator to move in unison. A mag release is slidably received within a slot in the chassis and capable of sliding between left, center, and right positions. A mag catch is rotatably received within the chassis and in operable communication with the mag release such that the mag catch engages a magazine when the mag release is centered and disengages the magazine when the mag release is in the right or left position.

What is claimed is: 
     
         1 . A firearm control system, comprising:
 a firearm frame having a chassis slot;   a chassis received in the chassis slot;   a first bolt actuator rotatably received within the chassis, the first bolt actuator having an upward position and a downward position, and configured to position a bolt rearward when in the upward position;   a second bolt actuator rotatably received within the chassis and operatively engaged with the first bolt actuator such that the first bolt actuator and second bolt actuator move in unison;   a magazine release slidably received within a magazine slot in the chassis and capable of sliding between a secure position and a released position; and   a magazine catch rotatably received within the chassis and in operable communication with the magazine release such that when the magazine release is in the secure position the magazine catch engages a magazine within a magazine well and when the magazine release is in the release position the magazine catch is rotated away from the magazine well disengaging the magazine.   
     
     
         2 . The firearm control system of  claim 1 , wherein the magazine release includes a left and a right position wherein the magazine release is in the release position when the magazine release is in the left or right position. 
     
     
         3 . The firearm control system of  claim 1 , wherein the first bolt actuator further comprises a magazine follower engagement arm configured to operatively engage a magazine follower to move the first bolt actuator to the upward position when a magazine is empty. 
     
     
         4 . The firearm control system of  claim 1 , wherein the first bolt actuator and the second bolt actuator each comprise a user push button or lever operable from opposite lateral sides of the firearm frame. 
     
     
         5 . The firearm control system of  claim 1 , further comprising a biasing spring configured to bias the first bolt actuator and the second bolt actuator toward the downward position. 
     
     
         6 . The firearm control system of  claim 1 , wherein the magazine release comprises button attachment points on opposite lateral sides of the chassis for engaging release buttons operable from either side of the firearm frame. 
     
     
         7 . The firearm control system of  claim 6 , further comprising a leg spring configured to bias the magazine catch toward engagement with a magazine and the magazine release toward a center position between a right and a left position. 
     
     
         8 . A firearm control system, comprising:
 a chassis configured to be received within a classis slot defined in a firearm frame;   a first bolt actuator rotatably received within the chassis between an upward position and a downward position, wherein the first bolt actuator engages a bolt of a firearm when in the upward position;   a magazine release slidable positioned within a magazine slot in the chassis between a secure position and a release position; and   a magazine catch rotatable within the chassis adapted to rotate in response to movement of the magazine release, wherein the magazine catch engages a magazine within a magazine well when the magazine release is in the secure position and disengages the magazine when the magazine release is in the release position.   
     
     
         9 . The firearm control system of  claim 8 , further comprising a magazine follower with a magazine follower engagement arm on the first bolt actuator to move the first bolt actuator to the upward position when a magazine is empty. 
     
     
         10 . The firearm control system of  claim 9 , further comprising biasing the first bolt actuator and the second bolt actuator toward the downward position with a spring. 
     
     
         11 . The firearm control system of  claim 10 , wherein rotating the first bolt actuator and the second bolt actuator comprises pressing a user push button or lever on either lateral side of the firearm frame to move both the first bolt actuator and the second bolt actuator to the downward position. 
     
     
         12 . The firearm control system of  claim 11 , further comprising biasing the magazine catch toward engagement with a magazine and the magazine release toward the center position with a leg spring. 
     
     
         13 . The firearm control of  claim 12 , wherein sliding the magazine release comprises actuating a release button on either lateral side of the firearm frame to move the magazine release to the left position or the right position. 
     
     
         14 . The firearm control of  claim 13 , further comprising securing the chassis within the firearm frame using a chassis pin that engages a pin receptacle in the firearm frame and a mounting receptacle in the chassis. 
     
     
         15 . A firearm, comprising:
 a frame having an upper receiver removably attached to the frame and a lower receiver integrated with the frame; and   
       a control system housed within the lower receiver, the control system including:
 a first bolt actuator rotatably mounted within the lower receiver and configured to engage a bolt of the firearm; 
 a second bolt actuator rotatably mounted within the lower receiver and operatively connected to the first bolt actuator for synchronized movement; and 
 a magazine release mechanism slidably carried by the control system and operable from opposite lateral sides of the frame to selectively engage and disengage a magazine. 
 
     
     
         16 . The firearm of  claim 15 , wherein the first bolt actuator comprises a magazine follower engagement arm configured to move the first bolt actuator to an upward position when a magazine is empty. 
     
     
         17 . The firearm of  claim 16 , wherein the first bolt actuator and the second bolt actuator each comprise a user-operable lever accessible from opposite lateral sides of the frame. 
     
     
         18 . The firearm of  claim 17 , wherein actuation of either user-operable lever moves both the first bolt actuator and the second bolt actuator to a downward position. 
     
     
         19 . The firearm of  claim 18 , further comprising a biasing spring configured to bias the first bolt actuator and the second bolt actuator toward the downward position. 
     
     
         20 . The firearm of  claim 19 , wherein the magazine release mechanism comprises a slidable magazine release with button attachment points on opposite lateral sides of the lower receiver; and a rotatable magazine catch operably connected to the slidable magazine release, wherein movement of the slidable magazine release causes rotation of the magazine catch to selectively engage or disengage the magazine.
