US12753983 - Lever-action firearm and kit for constructing the same

A receiver system comprises upper and lower receiver bodies, a lower receiver body, a bolt carrier, and an action-control lever. The upper receiver body is a semi-automatic firearm upper receiver body. The lower receiver body includes a stock mounting flange having a stock receptacle that is matingly engageable with a receiver engaging portion of a stock. The bolt carrier is slidably disposed within a bolt carrier receiving bore of the upper receiver body. The action-control lever has a hand loop and a first attachment arm having a proximate end portion thereof attached to the hand loop. The first attachment arm is pivotably attached at a distal end thereof to the lower receiver body for being pivoted between a battery-ready position and a cartridge-ejecting position relative to the lower receiver body. The action-control lever is attached to the bolt carrier through an articulating coupling assembly.
