Rated 5 out of 5 by from Tough and accurate Used my vortex scope for the first time in March of 2016 for a five day precision marksmanship course. I was very impressed with the accuracy of the tracking and the sharp image the scope had. It rained the first two days and despite a beaded front objective lense images were still crystal clear. Ranges were from 25 yds to 500 yds with most training at 100 to 500. The scope dialed accurate every time and the recticle didn't cover small targets which was a huge advantage in precision markmanship. Like it so much I purchased a second vortex scope for my target/varmint rifle. Keep up the good work vortex.

Rated 5 out of 5 by from Buying a Vortex PST is never a bad investment. After seeing these scopes used by folks on every shooting and long range forum that I visited, I decided to try one for myself. This scope is worth every penny that I paid for it. I was fortunate to catch them on a very good sale and there was simply no beating it for the money. The crisp field of view and excellent illumination are much nicer than its price range represents. I have noticed no bleeding of the illumination on any power level. Scope sighted in quickly and stays consistent on my 6.5 CM. Overall, I would have to say that spending your money on a Vortex product would never be a bad idea.

Rated 5 out of 5 by from Great optic for the money I Am running this scope on a Bergara B-14 in 6.5 Creedmoor. I purchased this optic because I did not have the extra cash to put out for the FFP model. This scope has performed very well. It seems to track well and come back to zero. The only thing I noticed that was a little off on mine is the parallax setting specified for 100 yards needed to be tweaked a little to get the best sight picture, but that's not a huge deal to me. The glass is very, very clear. I haven't had a chance to use it in low light yet, but I believe it will perform just fine. Overall, I'm very happy with my purchase. I may post another review once I get out and use it more and put it through its paces in the next few months.
