Re: sightron reviews?
I have a couple of Sightron SIII, and I have compared these to the Viper PST and Nightforce NSX.
The Sightrons are far from a Chinese Doorstop. I had mine out last weekend making hits at 1108 yards. The first 3 shots were all hits.
I have one scope on my 6.5 Creedmoor and another on my Tikka 7mm Mag. The Tikka is light and the 7mm Mag has lots of recoil. The sightron has held up fine. the nightforsce seems to be built more rugged, but the Sightron has held up fine to recoil and use in matches.
My gunsmith measured the scope and the MOA reticle was spot on. The scope tracking has repeatable zero. The tracking measured a 2% error rate. My gunsmith said the Nightforces usually have a much higher tracking error.
My friend that has the Viper PST has commented that the Sightron glass is clearer than his Viper. He is building up a new gun and ordered up a Sightron SIII for it.
I have compared my Sightron to the Nightforce NSX. The clarity of the glass seems the same on both scopes. The Nightforce had an advantage when looking through heavy mirage though. I think the Nightforce has slightly better contrast.
Overall, the Sightron has good glass (between the Viper and Nightforce), very good tracking, and is pretty durable. I sometimes consider the Nightforce NSX, then stop because the from what I have seen the improvement is very slight, and the cost difference is significant (~$1000).
