Overview
Zooming from a very low starting power to a mid-range top end, this first focal plane scope pairs a MIL reticle with an aluminum body. The wide field of view at low power helps find moving targets.
Low minimum power makes close shots quick, and the first focal plane reticle holds its marks true across the zoom. The listing's warranty entry says to see the manufacturer, which is less clear than a stated term.
Who it's for
Shooters who need quick target acquisition up close and the ability to reach out to moderate distances. Extreme long-range users should choose a higher-power optic.
Pros and cons
- Wide field of view at low power
- First focal plane reticle
- Mount options listed
- Top power limits long shots
- Warranty terms unclear
- Tube diameter not listed
Performance notes
A low minimum power gives a wide field of view for fast shots, while the top power adds detail for moderate distances. With a first focal plane reticle, holdover marks scale with the image so they stay accurate at any zoom. Illumination details are not given beyond the IR label.
