Big Beesa Platinum 10-50x60 on my Alpha Male FT rig. I bought two in Germany for the equivalent of 450 euro new (my wife has the other one atop her CR-X). Superbly bright, razor-sharp, rangefinds like nothing else I've seen, and is very insensitive to temperature changes. Wheels by Jon Harris.
If it would have a multi-aimpoint reticle, this would really be the Dog's Whatsits.
BSA 8-32 x 44 with mildot reticle (to go atop the HW97k). A far cry from the above Big Beesa in clarity, sharpness and rangefinding, but excellent value for money.
