For the money you get all the features of a $2000 scope. The glass is crystal clear the turret tracking is spot on evrything about this scope is high quality.

Got this for my new 224 Valkyrie Upper. Put a 30 MOA Scope mount and still had 20 MOA down elevation to spare zeroed at 200 Yards. I could have gone with a 40 MOA mount still be okay. I counted about 100MOA of elevation instead of the 70 MOA the specs had specified. The EBR-4 reticle is very similar to the NXS MOAR-T reticle of NF. Very clear. It has 25 MOA Turrets and feels very good. This scope will do what a NF scope will do. Planning on getting another one for my 308.

I've been running nightforce NXS series scopes for a few years and I decided to give vortex a try. And I must say I couldn't be more happier with my vortex Gen II it's has illuminated reticle with adjustment for the brightness and it has Parallax adjustment,a zero stop, and the clicks for windage and elevation are crisp and tracks true. I own two now for the price of one nightforce. Not knocking nightforce but come on a $999 optic versus $2,300 optic and to get the same performance an clarity you can't beat it. Good product!!!

I think this is an excellent scope for the money. The glass is clear and the reticle isn’t too crowded. Having a zero stop is a plus. I own a number of Vortex scopes, including a couple of PST’s, and they compare favorably with my Nightforce and Leupold scopes.

This is my second one of these! I love the illuminated reticle that can adjust for brightness. I am mounting this one on my 224 Valkyrie. My other is mounted on a 6.5 Creedmoor that was a huge success in a previous hog hunt.
