US 4,663,876 A · Stock assembly kit and rifle embodying the same

Abstract

A carbine comprising an improved stock assembly kit combined with a barrel and action assembly of preselected generic style or configuration, preferably that of a U.S. M1 carbine. The improved stock assembly includes a buttstock comprised of opposed concave half-sections which embrace and capture the trigger, receiver and operating slide mechanisms of the barrel and action assembly in upside-down orientation. A trigger assembly is mounted to the barrel forwardly of the buttstock section and is coupled to the trigger mechanism of the barrel and action assembly by a trigger slide which extends through the buttstock section. A forehand stock section is comprised of an opposed pair of stock half-sections which embrace that portion of the trigger assembly which engages the barrel and form a cavity for cooling air surrounding the barrel which extends therethrough. A concial flash hider is captured by the forehand stock sections surrounding the free end of the barrel and cooperates with apertures formed in the forehand stock sections for drawing cooling air into the cavity for cooling the barrel during firing.

Dependent claims

A rifle with improved stock assembly comprising:

a barrel and action assembly including receiver and trigger mechanisms having a barrel projecting therefrom;
separate hollow butt and forehand stock sections enclosing said barrel and action assembly, said receiver and trigger mechanisms being enclosed within said buttstock section and said barrel projecting therefrom through said forehand section;
a trigger assembly projecting from said forehand stock section and including trigger means for actuation by an operator;
and means slidable within said buttstock section coupling said trigger means to said trigger mechanism for firing said barrel and action assembly when said trigger means is actuated by an operator;
said buttstock section including means at one external end for abutting an operator's shoulder, and means internally of said buttstock section for locating said receiver and trigger mechanisms internally adjacent to said shoulder-abutting means in inverted orientation, such that said trigger mechanism and said trigger means project generally oppositely of the axis of said barrel and action assembly.
