I have the SIII 8-32x56 and it's a great scope. I would assume that the 10-50x60 would be comparable in every way. To me, it is optically as good or better than my 6.5-20x50 Mk4. The Sightron is brighter and has better contrast at all power settings. Mine has the LRMOA reticle and MOA adjustments. It's a great setup and I'm extremely happy with it. For the price, the SIII scope seem like one of the best deals out there in optics. When you consider that I can sell my used Mk4 and have almost enough to buy 2 of the Sightrons, the SIII looks like an even better deal.
