Abstract

A stock cheek riser that includes two side walls connected by a hood, which form a channel for receiving a stock. The stock cheek riser is sized and its front face angled to provide sufficient room for manipulating a charging handle of the firearm to which the stock is attached, when the stock is in a collapsed position.

a hood connecting a first proximal edge of the first side wall to a second proximal edge of the second side wall, and having a rounded surface;

a longitudinal channel defined by the first side wall and the second side wall;

a first mounting protrusion on an inside surface of the first side wall;

a second mounting protrusion on an inside surface of the second side wall; and

a front surface with a first portion that is substantially perpendicular to the channel, and a second portion that is angled toward a rear surface,
