Rated 5 out of 5 by from Makes shooting more fun I recently purchased a 6.5 creedmoor and stuck the Viper PST on it and wow what a combo that made! The PST has great clearity and is just amazing in low light! The super fun part was turning on the lighted reticle and being able to out shoot my buddies in the lowest of light conditions. Vortex gave a great instruction manual with the scope and I found another document on their website explaining the moa and or mrad systems which made getting to understand the scope a lot easier. I'm going to probably get a 6-24x50 PST for the creedmoor in the future and slap the 4-16x50 on a .223 for coyotes and other varmits. Needless to say I love my Vortex scope.

Rated 1 out of 5 by from Disapointment. I bought the viper PST FFP. The scope made it almost a year on the rifle and had to get the scope warrantied. The cross hairs were moving after every time the rifle was fired. Couldn't make a decent group for nothing. Took it back to the dealer I bought it from, and they bore sighted it and tapped on the top of the scope and found the cross hairs were moving. Was pretty disappointed in that for how much money was spent. Its not a very good hunting scope due to the uncapped turrets. Walking through the trees or rubbing up against your hunting pack will turn the turrets. Removed scope and went back to the cheap scope

Rated 4 out of 5 by from Great scope I bought this scope to put on my Tikka t3 varmint in 22-250. It is my coyote and prairie dog gun. I occasionally use it for varmint matches at the local range. The Good Glass is awesome on these. For my eye it is very clear through all mag levels. Low light transmission has been great. Turrets have a nice firm feel and audible click. Most importantly they track very well. Returning to zero is right where it was before. Zero stop is nice, it gets you close. Eye relief is very generous. The illuminated reticle with the ability to dim or brighten up the reticle depending on shooting conditions is nice. The bad I wish it had locking turrets like the new Gen 2 does now.
