Abstract

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.

Abstract

A firearm as disclosures herein comprises a main receiver body, a barrel, a breech bolt structure, a buffer assembly, a trigger group assembly, a bolt catch and at least one of an auto-sear, a magazine adapter and a breech bolt anti-rotation structure. The main receiver body is preferably of a monolithic construction whereby the handguard and breech bolt carrying bore can be manufactured from a single piece of material. The auto-sear is tripped by engagement with a buffer of the buffer assembly. The magazine adapter has an exterior surface structure engaged with a mating interior surface structure of a magazine well space of the main receiver body. A distal end portion of the breech bolt anti-rotation structure is engageable by the buffer for limiting forward travel of the buffer when the barrel is detached from the main receiver body.

Abstract

A rifle kit comprises a rifle receiver structure having a central passage configured for having a substantially as-manufactured breech bolt of a pistol mounted therein and has one or more shoulder stock mounting portions configured for having a shoulder stock structure engaged therewith. A substantially as-manufactured breech bolt of the kit is configured by an original equipment manufacturer (OEM) thereof for being mounted on a pistol receiver body configured by the OEM. The rifle barrel is mountable within the central passage of the rifle receiver structure. A chamber end portion of the rifle barrel is configured for engaging a mating portion of the substantially as-manufactured breech bolt. A shoulder stock structure of the kit includes a receiver structure engaging portion configured for allowing the shoulder stock structure to be mounted on the rifle receiver structure exclusively through engagement with the one or more stock mounting portions of the rifle receiver structure.
