## Abstract

Disclosed herein is a windage-adjustable optics mount with at least one external windage adjustment tool. Further disclosed herein is a method of adjusting the windage of an aiming device mounted on an adjustable windage optics mount by way of an external windage adjustment tool. The external windage adjustment tool may provide a means for adjusting windage by incrementally pivoting one end of a rail, upon which an aiming device may be mounted, relative to an opposite end of the rail, thereby allowing the rail to function as a windage-adjustable rail. A windage-adjustable rail may include an optics mounting feature, for example a Picatinny rail (also known as MIL-STD-1913 rail), and an arrangement of holes and recesses necessary for alignment and for securing to a base member.

## Claims

### Claim 1

An adjustable mount system for aiming devices comprising:
a base member configured to attach to a firearm;
a rail configured to attach to an aiming device and further configured to pivotably attach to a pivot point on the base member;
wherein the base member further comprises a first alignment marking, and
wherein the rail further comprises
a second alignment marking; and
at least one viewing hole configured to make visible the first alignment marking when the rail is pivotably attached to a pivot point on the base member.

### Claim 2 (depends on 1)

The adjustable mount system of claim 1, further comprising an adjustment tool configured to engage the rail so as to rotate the rail about the pivot point.

### Claim 3 (depends on 2)

The adjustable mount system of claim 2, wherein the base member further comprises a first alignment marking, and wherein the rail further comprises:
a second alignment marking; and
at least one viewing hole configured to make visible the first alignment marking when the rail is pivotably attached to a pivot point on the base member.

### Claim 4 (depends on 2)

The adjustable mount system of claim 2, wherein the rail further comprises a first region, and wherein the adjustment tool is configured to mechanically engage the first region so as to pivot the first region about the pivot point.

### Claim 5 (depends on 4)

The adjustable mount system of claim 4, wherein the adjustment tool further comprises an adjustment screw that engages the first region.

### Claim 6 (depends on 4)

The adjustable mount system of claim 4, wherein the base member further comprises a first alignment marking, and wherein the rail further comprises:
a second alignment marking; and
at least one viewing hole configured to make visible the first alignment marking when the rail is pivotably attached to a pivot point on the base member.
