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 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.

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 5 out of 5 by from Incredible optics at a great value I have only owned this scope for two weeks and i could not be happier. Still getting used to mrad over moa but the scaling is similar with the .1 mrad config. I love that you can zoom in without any additional adjustments and ranging with the reticle is easy. Incredible clarity and the almost 4 in eye relief on the scope makes it easy for my son to feel comfodtable as well. I could keep going on and on but i would definitely rank this model up there with my nightforce nxs and uso scopes and saved 1k-2k in cost easily. Vortex has earned their place among my arsenal!

Rated 5 out of 5 by from Perfect for my .308AR! I have this scope mounted on my "Frankenstein" .308AR. The rifle is a mix of parts that's pretty much a homegrown DPMS SASS. I looked at and through plenty of scopes prior to purchasing this one and the clarity is on par with scopes that cost three times as much. I love the FFP feature and the illumination settings with an off setting in between each. With the addition of a throw lever the magnification goes from 4 to 16 with ease and stays where I leave it. I simply love this scope and believe it is the best firearm related purchase I've made in a long time.

Rated 5 out of 5 by from Well worth the money!! I've never spent more that a couple hundred dollars on a scope. I decide to build an AR-15. I've heard your glass should cost as much as the gun. In this case it was really close. As soon as I got the scope I knew I made the right choice. I've been reloading for the gun and this scope is a great help. Even at 100 yards I can see where I hit the target so it allows me to go to range alone and with less equipment. I don't have hours upon of hours behind a gun and the FFP is a feature I love. If you buy this scope you will not regret it.

Rated 5 out of 5 by from Best warranty I bought this scope from a fellow military man....I wasn't sure if this was the scope for me but with the features and the clarity this product provided I knew it was the one... The warranty alone was a deal closer... I have piece of mind knowing that my scope is covered for anything I would put it through... And the ViP warranty transfers from owner to owner, so if you posses the product, then you posses the warranty. Thanks viper for quality glass! I will be making my purchases for binos, rangefinder, and spotting glass from Vortex!

Rated 5 out of 5 by from It just keeps getting better I just upgraded from a Viper 4-12x40 to the PST. 4-16x50 FFP on my .243! I mounted it bore sighted it that night. Took it to the range the next day and had it dialed in in 3 shots (I shot plent more to check my self). I took it out and checked the longer range sighting at 200,300, & 400 yards. It dialed right in using the vortex LBRC. I have never had a scope perform this well right out of the box! I took it coyote hunting right after my field test and had a one shot kill at 425 yards! Another great product from Vortex!!!

Is this scope good enough for .50 BMG?

Asked by: Redclaw
The Viper PST would work very well on a .50 BMG, make sure you use a good quality set of rings like our Precision Matched Rings and follow our torque specs of 15-18 inch pounds with no Loctite.

I have purchased a Vortex Viper PST 4-16X50 FFP scope for my Savage model 10 BA Stealth 6.5 Creedmoor rifle, can you tell me what the best rings would be for this combination?
Asked by: its4u21dr
