Also with integrated diopter that provides fast focus ability to keep target image clear.

Rubber sleeve cover protects the body from harsh scratch and impact to last a long time outdoor.


  • Very affordable for casual shooters


  • Out of spec for some 30mm ring mounts

Before you pick up a magnifier scope, make sure you know which mount you want.

There are fixed mounts, flip to side mounts or twist mounts.

Flip to the side mount is the most popular because you can basically tug the scope away if not needed, or flip it back when you need it.
