## 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.

## Claims

### Claim 1

A stock riser, comprising:
a first side wall and a second side wall, wherein the first side wall and the second side wall are opposing one another;
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,
wherein the first side wall includes a first chamfered portion at a first distal edge, and the second side wall includes a second chamfered portion at a second distal edge, wherein the first chamfered portion and the second chamfered portion are angled toward the longitudinal channel.

### Claim 2 (depends on 1)

The stock riser of claim 1, wherein the first mounting protrusion is positioned opposite the chamfered portion on the inside surface of the first side wall.

### Claim 3 (depends on 1)

The stock riser of claim 1, further including structural elements on an inside surface of the hood.

### Claim 4 (depends on 1)

The stock riser of claim 1, wherein the hood interfaces the first side wall at an obtuse angle.

### Claim 5 (depends on 1)

The stock riser of claim 1, wherein the first side wall and the second side wall angled toward each other, wherein the angle is less than 90 degrees.

### Claim 6 (depends on 1)

The stock riser of claim 1, wherein the interface of the front surface and the first side wall is chamfered.

### Claim 7 (depends on 1)

The stock riser of claim 1, wherein the first and second side walls and the hood are made of a material that includes carbon-fiber infused nylon.

### Claim 8 (depends on 2)

The stock riser of claim 2, wherein the chamfered portion of the first side wall is angled inward toward the channel.

### Claim 9 (depends on 1)

The stock riser of claim 1, wherein the first length is 3.5 inches or less.

### Claim 10 (depends on 1)

The stock riser of claim 1, wherein the length limits the number of mounting protrusions on each side wall to one.
