Overview
A precision rifle hunter gets a big power span, a large objective and an MOA reticle here. The body is aluminum, the mount type is listed as Weaver, and an instruction manual comes with it.
A large objective gathers light for dim hours, and the span of magnification covers many distances. The listing leaves out the tube diameter, focal plane and turret details, which hunters need to choose rings and plan holdovers.
Who it's for
Rifle owners who shoot at mixed distances and want a flexible optic. Buyers who need exact ring sizes should confirm the tube diameter first.
Pros and cons
- Wide zoom range
- Large objective lens
- Tube diameter not listed
- Focal plane not stated
- Turret details missing
Performance notes
Zoom range sets how wide the view is at low power and how much detail appears at the top. A larger objective gathers more light, which helps in dim conditions but adds weight and height over the rifle. The reticle subtensions must match the turret units for holdover math.
