Viper® PST™ 4-16x50 Riflescope

The Viper PST (Precision Shooting Tactical) riflescope boasts features associated with top-tier riflescopes, yet comes in at a street price under the $1,000 mark. Matching reticle and turret measurements allow accurate, fast dialing of shots. The one-piece 30mm tube, precision-machined from a single solid block of aircraft-grade 6061-T6 aluminum, offers ample windage and elevation adjustment. Born from an intimate understanding of riflescope design, forward-thinking engineering, and open ears to a market incredibly vocal about what it wants in a riflescope, the Viper PST series delivers the performance and features tactical shooters demand at an economical price.

Note
Also available with a first (FFP) focal plane reticle—an important option for many precision shooters.

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 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 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.

Rated 2 out of 5 by from Not a long distance scope I bought this scope on 11/27/2015. I have had it on 3 different rifles. Its very heavy for a hunting rifle and the optics are not clear enough for a for long range target rifle. The scope tracks well and the adjustments are precise, I simply cannot see where to hold at the 700 yard 8 inch gong. I own 4 Leupolds, two are similarly priced and 2 mark 4s. The optics are much clearer on all 4. The optics are not terrible and work out to 600 yards but beyond that you can't see the target. I bought this at Cabelas on black Friday, there were Leupolds in one stack and Vortex in the other stack, I wish I picked from the other stack. I'm going to return it, maybe mine is defective as most the other reviewers really like their scope

Rated 2 out of 5 by from Disappointing long range performance I have had this Viper PST 4-16 EBR-1 for a while now and have always felt that its performance fell somewhat short of what might be expected if all the reviews and manufacturer's hype were to be believed. Yes, it's a nice scope - well put together, excellent reticle, great turret feel and function and smooth zoom and focus rings. However, the focus ring does not bring targets into sharp focus; a target at, say, 200 yards will be in focus from 70 to 500 yards as indicated on the focus ring. Reducing parallax then takes far more time. Targets at 600 yards and beyond cannot be brought into sharp focus. The focus ring really ceases to have much effect past 200 yards. This scope is twice the price of a Hawke Sidewinder but performance is no better, hence my disappointment. A look through a similarly-priced Nightforce scope has brought home to me just how mediocre the Viper is in comparison at longer distances. I was looking forward to a rare opportunity to shoot my .308 at longer ranges (up to 850 yards!) using the Viper, but came away at the end of the day feeling that (a) there may be better scopes available for around the same price, and (b) while the image quality was OK, the side focus operation was poor.

Rated 5 out of 5 by from Absolutely amazing optics.! I use this scope on my ar-10. I have shot up to 600 yards and viewed out to a 1,000 and the clarity is always perfect. The zero stop feature is great as you never have to worry about loosing your zero no matter how many times to change elevation even if you forget where you left it. After over 1,000 rounds my zero is still spot on and am easily able to quickly adjust my distance accurately and consistently. I do recommend this scope to all of my friends and will buy another one for my next build.

Rated 5 out of 5 by from Great on the range or in the field! I have this scope on my 6.5-06 rifle, and it is great! Have taken 3 of my biggest whitetails to date using this rifle/scope combo, out to a range of 225 yards...I have also shot steel plates out to 600 yards, hit at the 10 o'clock postion of a 2" dot the first shot at 600 yards, scope was spot on while dialing elevation and wind, then returned to 100 yard zero with no problem whatsoever! I highly recommend this optic for anyone wanting an affordable option for both hunting and target shooting!

Rated 5 out of 5 by from Saving for my next one I put this scope on my varmitt gun and it has done nothing but impress me. It is crystal clear, the reticals are great, and holds very true very good as well. Living close to their location near Madison, WI, they stand true to have the best warranty in the business with an even quicker turn around time for repairs that i have had on previous purchases(binoculars). I'm looking forward to buying another gun to put another one of these scopes on soon! Thank you Vortex.

If I wanted to mount the 4x16-50 on a Ruger American Predator with a 1" scope rail and wanted to shout out to 1000yds what height scope ring would you recommend to allow correct adjustments to that range?

Asked by: James
I recommend a 20 MOA one piece picatinny rail with a set of our 30 mm Precision Matched Rings - .97" height for your setup.

I have the viper pst sfp moa 4-16x50, messing around with strelock pro and was wondering what power it was calibrated at for ranging?

Asked by: Crowley92
The reticle in the second focal plane Viper PST 4-16x50 subtends at its listed values when the scope is at max magnification.

Can you advise what caliber, weight, and length of barrel were used in testing for the EBR subtensions. Thank you.

Asked by: FLpete
The subtensions on the reticle are not set up for a caliber, they are set up in MOA or MRAD and are evenly spaced hashmarks. Give us a call at 800-426-0048 ext 5 if you would like to discuss this further.

Can the reticle be seen clearly without installing a battery and are turret caps available?
Asked by: Glen
Yes, the reticle will be black when it is not illuminated. There are not turret caps for this scope as the turrets are designed to be uncapped.
