all my scopes are set at 1.5 height, as I use both Night vision and thermal. Actually hunt more at night than day. I have an RH25 and mostly use it for hand held. My mounts are Spurh. Built like a tank. Not cheap. lotta debate on all scopes. I have Leupold. For a RH25 gotta be good low power. 1x6, 2x8, or 2x10. Mostly use in the 2 to 6 power range otherwise the image starts to pixilate.
