That is the scope I have on my night time rifle. It does check out accurately. At night though it is a shame the range figures do not illuminate....not that I have shot much further than 100yds at night!
I'm currently (in daytime) using the PX focusing to judge rang but it is far from ideal.
The blurb says, iirc, on 13x the distances become meters. If your foreign lol. Or from Canada, or down under.
