I love my Sightron too. SIII 6-24x50 LRMD. I do have one issue that I am going to fix. I find the crosshairs on the Mildot reticule too be a bit thick, too bad they didn't have a Mildot cross-hair like the Nightforce with thinner lines and hollow dots, that would be awesome.
I am sending my scope to Sightron in a week to have the reticule swapped out for the LRMOA reticule at the Sightron custom shop. It is thinner overall with a small dot in the centre. It's much nicer for long range precision shooting. Overall great scopes for the money, very bright, hold their adjustments, excellent quality and construction, service is great, and the distributor in Canada Hirsch Precision (Peter Dobson), is great to deal with. I'll buy another for my next rifle for sure.
