Benefits of technology

The solution provides a more reliable and precise adjustment mechanism for windage and elevation, reducing wear and fatigue, and increasing the range of motion, while maintaining the strength and durability of the scope.

Problems solved by technology

In contrast, many conventional system rely on forward spring designs with ball seats that have machined grooves that cause sticking and jumping when adjusting the windage or elevation.
To convert the rotation motion to axial motion of a lens does not need multiple large profile moving components or layers inside the central body that occupy additional space inside the central body and interfere with the scopes normal operation and reduce optical performance of the scope.

Embodiment Construction

[0050] These and other aspects, advantages, and features of the present teachings will become apparent from the following detailed description and with reference to the accompanying drawings. In the drawings, similar elements have similar reference numerals. To assist the description of the scope and its components, the following coordinate terms are used. The terms proximal and distal, which are used to describe the disclosed embodiments, are used consistently with the description of the exemplary applications. The terms proximal and distal are used in reference to the head of the user looking through the scope. That is, proximal components are nearer to the user than distal components.

[0051]FIG. 1 illustrates a scope 100 that has a zoom assembly 103 for providing selectable zoom thereby controlling the apparent distance to an object viewed through the scope. The zoom assembly 103 includes the zoom selector ring 105 that is disposed along and surrounds a main body 110 of the scope...

Abstract

A scope for a firearm can be used for a gun sight. The scope comprises a main tube that contains imaging optics therein. In certain embodiments, the main tube comprises a single continuous tubular body extending uninterrupted from a widened proximal end portion through a narrow medial portion to a widened distal end portion. A side focus assembly is positioned along the tubular body. The side focus assembly is used to vary the position of optics within the scope to adjust the overall focus of the scope.
