Overview

The Nikon 16407 Switchview Power Adjust Tool is a purpose-built throw lever designed to make magnification adjustments on compatible Nikon Monarch riflescopes faster and more intuitive. Constructed from durable aluminum, the lever clamps securely around the scope's zoom ring and extends outward to provide a convenient handle that can be flipped quickly between magnification settings. This is particularly valuable in situations where speed matters—transitioning between close-range and long-range targets—or when fine motor control is compromised by cold weather, wet conditions, or heavy gloves.

The Switchview is engineered specifically for Nikon Monarch 3 1-inch, Monarch 5 1-inch, and Monarch M-Series 1-inch riflescopes, ensuring a precise fit on the zoom ring without slipping or wobbling. Installation is straightforward with a tool-free clamping system, and the lever can be removed just as easily without leaving marks or affecting the scope's function. Its compact, low-profile design keeps the overall scope setup streamlined and avoids interference with lens caps, scope rings, or other mounted accessories. At just 1 inch in size with a clean black finish, it integrates discreetly into most riflescope configurations.
