So I spent yesterday at the range with 3 rifles 7mm Rem with a Riton, a 7-08 with a Vortex and my Whelen with a Leupold. All 3 perform excellent the Riton and the Vortex are in the upper magnification range and the Leupold is a 3x15.The glass on the Vortex and Riton are excellent but the glass on the Leupold is outstanding, of course the Leupold is 2.5 times the price I wonder how a 1200.00 Riton and Vortex would compare but thats not likely to happen with my budget
I got to look through a $3,700 Vortex mounted on a long range target rifle and will say it appeared to be outstanding but I wouldn't expect anything else at that price point.
I know the Crossfire II and Diamondback get good reviews at their price point and I certainly buy many Chinese products but I try to avoid it if possible.
