Most Helpful Positive Review Rivals Leupold VX III in Brightness and Clarity
Before ordering the Vortex Diamond Back 4-12x40 I ordered a Nikon Pro Staff 4-12x40.

Great scope

by David, Verified Owner from CA, United States Written on April 11, 2026
I just want to complement Vortex on their warranty and customer service. My scope went completely blurry after taking a couple shots at the range. I called up Vortex and they had me ship it in for free. Ended up sending me a completely new scope! Hopefully this one won’t give me any problems.
