Overview
A first focal plane reticle changes size along with the magnification on this variable power riflescope. The reticle is marked in MRAD, and an aluminum body carries the optics.
A wide magnification range and a large objective lens give flexibility between close and distant targets. The listing leaves out tube diameter, eye relief, parallax and turret travel, which decide ring choice and shooting setup.
Who it's for
Rifle owners who dial and hold in milliradians and want one scope across near and far targets. Shooters needing night vision, an illuminated reticle or a known tube diameter should confirm details first, since the listing offers none of them.
Pros and cons
- Wide magnification range
- Large objective lens
- First focal plane reticle
- Lifetime unconditional warranty
- No night vision
- Tube diameter not listed
- Eye relief unspecified
Performance notes
The objective lens diameter sets how much light enters the scope, which matters most at dusk, while higher magnification narrows the view. With the reticle in the first focal plane, its marks scale with the zoom setting, so MRAD holds remain valid at any power. Mount height and ring fit decide eye position behind the glass.
