Light Streams, are excellent scopes I have one . I did put mine on my HW100SK . Ive still got but im thinking of selling it .Then change my mind . Its 4.5-14×44.
I have Hikmicro LRF day night scope.
The LightStream , your talking about i cant remember the reason however 5-20 is not as good as the 4.5-14×44FFP. But still good .even though it was more money .
