Overview

This magnifier is built for shooters who want a quick way to add 3x viewing to an AR-height red dot sight without giving up the option to run unmagnified. The flip-mount design lets it move in and out of position with a push-button action, making it practical for changing distances or target types. Fully multi-coated optics are included to support light transmission, while the hard-coat-anodized aluminum construction and nitrogen purging are aimed at dependable use in varied conditions. It also supports lower 1/3 or absolute co-witness mounting heights, giving it a flexible fit for common red dot setups.

Considerations & Trade-offs

  • Adds 3x magnification to a red dot setup, so it is intended for shooters who want magnified and unmagnified views rather than a dedicated optic.
  • Designed for AR-height red dot sights and supports lower 1/3 or absolute co-witness mounting heights, so compatibility depends on the specific setup.
  • At 11.9 oz, it adds noticeable weight compared with running a red dot alone.
  • The flip-mount design prioritizes quick transition, which may be less streamlined than a fixed-magnification setup for users who do not need frequent switching.
