The 10mile series look very nice
The 4.5 - 30 10 mile is made by LOW in Japan. There are several other brands that use the same scope body and internal components. Each brand will have their own specs as to the glass quality, reticle styles, turret styles, etc.. But they are all basically the same scopes.
Athlon Cronus BTR
And some other brands.
The prices vary pretty wide between all of them, but they all are pretty much the same scopes, some have different features, and better glass quality.
