Lever action firearms have an upper frame defining a bolt passage, a bolt carrier assembly received in the upper frame and operable to reciprocate between an open position and a closed position, a lower frame defining a magazine well configured to removably receive a box magazine, the lower frame removably connected to the upper frame by a transverse takedown pin, an action lever movable between a retracted position and an extended position and having a first pivot, and pivotally connected to the lower frame at the first pivot, a first link pivotally connected to the lower frame, a second link pivotally connected to the bolt carrier assembly, the first link and second link pivotally interconnected to each other, the first link defining a cam path, and a cam follower on the action lever operably engaged to the cam path such that movement of the action lever generates movement of the bolt carrier assembly.

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.

A firearm is provided that comprises a barrel, a magazine tube below the barrel, and a handguard with first and second portions. A clamp between the handguard portions has a main body with deformable lugs and a fastener. The handguard's first portion features an arcuate surface for the barrel and a bore for the magazine tube. The lugs move inward and downward, securing the handguard. The clamp is positioned within a recess between the handguard portions. Fasteners are accessible through apertures in the handguard. The clamp contacts both the magazine tube and the barrel when tightened. The clamp includes a main body and deformable lugs, with a fastener to secure the handguard. The lugs are deformable, made of various materials, and designed to bend upon tightening. The method involves positioning and tightening the clamp to deform the lugs and secure the handguard.
