I have a 3-12 LRTSi that I am quite fond of as well, will hunt with it for the first time this fall. I did just recently find out about a new for 2020 model from Sightron, the S-TAC 3-16x42 with a FFP illuminated mil reticle. MidwayUSA is bringing them out at an unbelievable price ($311!!!) so I decided to try one out. It will be delivered tomorrow, so I'll circle back once I get it out of the box and can compare it to my LRTSi
The Meopta Optika6 3-18 with the MRAD reticle may be the closest as it has a similar bold donut feature for low magnification use, illumination, and capped windage turret.
