The Viper PST Gen II hands an unfair advantage to shooters who seek to keep the upper hand in every situation from close quarters to long-range shots. The illumination dial is cleanly integrated into the side focus adjustment knob for easy access and streamlined performance. The glass-etched reticle offers shooters highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.

Rated 5 out of 5 by from Viper PSTG2 5-25x50mm FFP MRAD Purchased the PSTG2 5-25x50mm FFP MRAD in April and after a long awaited backorder time it finally arrived. I mounted it to my .308 Ruger Precision Rifle, sighted it in, and verified my DOPE. Result: dead center at 1000 yds. I could not be happier, the zero stops are a breeze to set, the glass is excellent, and I absolutely love the reticle design. This is taking the place of a borrowed PSTG1, and I am very much looking forward to taking it to a competition. I definitely recommend getting a set of the Vortex Defender caps for it, the cheaper caps from other manufacturers break very quickly. Great product Vortex!

Rated 5 out of 5 by from Awesome scope for price I coupled the Viper PST Gen II 5-25x50 FFP with my new Ruger Precision 6.5 rifle. At first, I couldn't zero. My advice, don't trust the gun store when they say they have bore sighted. Do your own bore sight. After the bore sight, it was only a matter of a few rounds at 50 yds and a few more at 100 yds. I'm an amateur and did it in no time. This is my first long range rifle. I was able to hit 3 rounds within .25 inches. The nice features like bringing the scope back to zero and the 11 level of illumination are great for an amateur. Going to try to this out at sniper training school next summer doing longer distances at 800 yds. Can't be beat at $ 1500 CAD.

Rated 5 out of 5 by from Excellent long range optic I purchased this scope for my 50 BMG, planning on shooting it out as far as my property will allow, ~1000 yards, give or take. From the picnic table, it's 900 yards to a 24" steel plate. After zeroing at 100yds, I tried using the excellent EBR-2C (MOA) reticle for compensation at 400 yards (the subtensions matched my ballistic calculations perfectly), then dialed the correction which, again, worked perfectly. Stepping it out to 900 yards, I nailed this plate on my second shot with a milsurp tracer, using only the reticle for compensation. I'm about to purchase a second one of the these scopes my 6.5 Creedmoor M1A, with the same precision matched 30mm rings.

Rated 5 out of 5 by from Great scope for anything. Iv had this scope for a few months now, clarity is a vastly improved, relocating the illumination to inside the paralax knob was a nice sleek choice also clicks off between every increase or decrease in illumination is a added bonus, leaving it between 3 and 4 gives great low light or some added color against a black background. Scope tracks true, ebr-c2 reticle has a lot of information on it without being crowded and overwhelming. The booklet gives you all your MIL sizes for your hash marks and dots. It has a small open center so no issue with thick lines at 25 power covering dots. Sunshade comes with is a.mice

Rated 5 out of 5 by from A Must have for shoot long range! I purchased this optic to pair with my Ruger Precision rifle. After having great luck with another Vortex Optic on my R700 I figured this would pair with the Ruger great. It has no problem reaching out past 1000yds and then some. The illuminated FFP reticle allows you see exactly what your point of impact is with amazing clarity. The turrets adjust quickly with a nice textile click with each turn. The illumination is crisp with no blur off like other optics. I paired this optic with the Vortex Defender Lens Caps which fit perfect and provide great protection.

Rated 5 out of 5 by from Fantastic optic. I currently have this installed on a savage 10ba stealth evolution in 6.5 creedmoor. I honesty don’t believe that you could find a better optic at this price point. The glass is extremely clear and the adjustments are spot on. I have taken it out to 900 yards so far with this optic and was able to get repeatable dialing and amazing accuracy with this combination. First round impacts are a breeze. The glass isn’t quite on par with the razor HD Gen 2 but the adjustments seem as accurate and it’s half the price so what can you expect? If you are looking for the best optic that you can get at this price point I wouldn’t even waste time looking around. This is the optic for you.

Rated 5 out of 5 by from Crystal clear, great range, solid scope! I bought this scope for a Ruger Precision Rifle in 6.5 Creedmoor. Looking through the scope it is crystal clear. Being that it is 5-25 power you have a great range to cycle through. At 5 power, while not ideal, you can shoot at shorter ranges ok, but at the highest power, you can get good visuals of targets at much further ranges. The scope is built extremely well, the turrets have nice tactile clicks and everything is very solid. My only complaint, which is mostly due to it being so new, is the illumination knob is very tight, and bare handed it is difficult to turn, but with some gloves, it was much easier.

Rated 5 out of 5 by from Excellent choice for PDogs; can't be beat If you're considering an extended range variable scope that won't bankrupt you, the Vortex PST Gen II 5-25 FFP is a great choice. From the turret adjustment, magnification range, optical clarity, or durability, this optic has you covered. This piece sits on top of a 20" Varmint MSR that I built for a Prairie Dog hunt. During the hunt, I was able to consistently engage targets from 30 yards to over 500 yards. Since this is a FFP riflescope, I was also able to use any magnification to spot for my hunting partner and call out adjustments to his POA. The turrets are surprisingly good for a scope I this class as well. If you need a scope in this role, you can't beat the feature-packed PST Gen II for the money.

Rated 5 out of 5 by from Knocking them dead My son bought this two months ago ready for the elk and deer season and getting ready for a moose hunt in British Columbia ( senior gift). He saved all summer and sold his last Vortex to buy this one.You can't ask for a better rifle scope. The main purpose of buying this one was for the long range ability and to take on his moose hunt. So if he has to take a five or six hundred yard shot he will. Will be bringing this scope to Crystal Lake Resort to bag that trophy once in a lifetime Moose, bear, and wolf this September.

Rated 5 out of 5 by from Long range and Super Clear I have been looking for a scope that would multi task as a hunting platform and a long range tactical application for about a year. Well problem solved, VIPER PST GEN II 5-25X50. I have put this scope up against all the top brands and it out shines them all. This is the one scope that will give you all you need. Todd G Robertson.

Rated 5 out of 5 by from Great scope Bought this recently as an upgrade to my gen I pst. Moving the lighting button to the same spot as parallax adjustment is nice, though the lighting is a bit too hard to operate for my liking. The RZR zero stop can be a little hard to set up if you want to be able to go "above" zero. (I zero for 200m, but want 8-10 clicks available for closer ranges). These two things doesn't subtract from so much from the overall impression that I will consider anything but 5 stars. Keep up the good work Vortex

Rated 5 out of 5 by from The scope that everyone wants to try I had toiled in low end scope purgatory for years. Once the chance to participate in a long range shooting competition came up, I know it was time to move on up. Every review, every expert said that this scope was the one. They were right. The clarity of glass, precision of adjustment, and crisp FFP reticle can't be touched at this price point. This scope sits atop my Ruger Precision Rifle 6.5cm and it is basically a laser gun at this point with the 140gr ELDs. On top of all this, I can't say enough about the amazing warranty. I thought when it came and I had it mounted that it had an issue with the windage turret tracking. I called Vortex, and they encouraged me to send it it, which I did free of charge. I week or so later I got a call. A real person, called me, on my telephone, and spoke to me about it. Adam said that they couldn't get it to replicate what I was saying in the factory, so he wanted my permission to take it out in the field and see if they could learn more. How amazing. In this day and age, a real person, wanted to help me with a product, and on their own time no less. He mounted the scope to his own rifle and took it for a spin. Needless to say, I was the one who had a made a mistake, not them. They were happy to put my concerns to rest, and I couldn't be more happy with the product, or the company. Many claim to have a "lifetime" warranty. Vortex delivers the goods.

Rated 5 out of 5 by from Awesome scope Just mounted this scope on my RPR 6.5 CM. When zeroing at 100yds my bore sight kept floating. Since my LGS has a 100yd zero range decided to let the gunsmith reset the scope. After having the scope reset, only took 4 shots to be zeroed with 1/2" group at 1/2" high at 100yds. Absolutely awesome scope. Thank Vortex for making this scope affordable for people getting into the precision shooting sports. Good glass at an affordable price. Thanks again Vortex, and thanks to the guys at Bullet & Barrel (Huntsville, AL) for making sure my scope was properly mounted on my rifle. (Yes I know a shameless plug for Vortex and to one my LGS.)

Rated 5 out of 5 by from Switch from PST to PST II - is it worth it? Absolutely! My girlfriend was using Vortex PST 6-24x50 on her RPR for over a year. I have it on some of my rifles for years as well. But she wanted some scope with Zero stop and christmas tree reticle. So we changed it for Vortex PST II 5-25x50 FFP MRAD EBR-2C. And we love it! The reticle is just great. Not super busy but if we need some marks for hold over - we can find them fast and easy. Open center helps with fine aiming... The turrets are just great. 10 mils per revolution which is enough for 1000m. Zero stop can be adjusted at any value (we are usually adjusting it 0,5 MIL under) and zeroing itself can be fine adjusted even in between the clicks. The scope is mechanically just great and well equipped. Optical performance is very good. It can stand against scopes in much higher price range... Overal - it is just fantastic scope.

Rated 5 out of 5 by from Nothing Better for the money The quality of this optic is as good if not better than scopes at twice the cost. From 100 to over 1000 yards, this is my go to optic. Tracking tests have been right on and the clarity is amazing.

Rated 5 out of 5 by from Amazing optic!!! I finally got the Vortex Viper PSR GenII 5-25 with the EBR-2C reticle and I couldn't be happier, I mounted it on my custom built rem 700 in .308 . I have already shot one match with it and it amazing. The turret dials are firm and crisp , the zero stop feature is perfect, and parallax adjustment is very precise, and to top it all off the illuminated reticle is a great feature for low light conditions. I would highly recommend this scope to anyone looking for a great quality optic. Thank.

Rated 5 out of 5 by from 5-25 Gen2 PST Got this scope for a .223 PRS trainer rifle and am very impressed. Scope is a vast improvement over the gen 1. Glass is great, reticle is the ebr-2c which i love. turrets are pretty good for the class of scope this is in. I would highly recommend this scope to anyone.

Rated 5 out of 5 by from This is a really good scope I have verified that reticle dimensions are spot on, mrad clicks are spot on and overall feeling is really solid. I had the gen1 scope earlier, and the main flaws are all gone in this model. 10mrad turret rotation and zero stop being the biggest improvements. Only flaw I have found is that my reticle is canted about 1,5 degree clockwise. You can barely see this by naked eye, but I was told that this goes to tolerances. It's a nuisance especially in competitions when shooting at distances 800m+, when you maybe shoudn't trust your reticle windage correction on second shot. But I can live with that. I have tested many $3k (and $1k) optics, and my honest opinion is that my viper has clearer picture than any of them.

Rated 5 out of 5 by from Great Optic I bought this optic several months ago to top out a 6.5 Creedmore chassis rifle. I zeroed the rifle in South Florida and I flew out to Colorado to shoot 1000 yards on vacation. The optic held zero after being transported on an airline. The glass is very clear and the turrets have an audible and tactile adjustment. Overall great construction of the optic. I have the EBR-2C MOA version which provides a great system for wind and elevation holds. Overall a fantastic optic.

Rated 5 out of 5 by from Quality Product For the money this scope is hard to beat. The scope had much clearer glass compared to several other scopes in this price range. Knurled turrets are a nice feature with solid clicks when adjusted. With an illuminated reticle, FFP, clear glass, solid construction, and a great warranty behind the product, the PST GEN ll is hard to beat. Very happy with mine.

Rated 5 out of 5 by from A Snipers Perspective An upcoming Wyoming elk hunt in November had me scurrying to find some glass for my 300wm. Having served as a sniper team leader for 4 1/2 years in the Army, I knew I needed something comparable or better than military issued glass. I decided on the PST gen 2 because of my budget and on many 3rd party sites it ranked extremely high. I was surprised at the clarity and durability. Two weeks in the Wyoming mountains in waist high snow proved to be no match for the PST Gen 2. Not having lens caps, I did my best to keep snow and ice off of the lenses. The constant wiping of snow off the lenses with my gloves didn’t leave a single mark. FYI I thought I’d never use the illuminated reticle. Last morning of the hunt, 6am and 11 degrees out, My cousin and I are freezing our a** off sitting in snow on top a mountain. Just as the sky turns from black to blue, what I though were boulders across the canyon in front of us, began to move and I noticed they had legs. Elk. Too dark to see my reticle, I actually had to turn on the illumination. I tell my cousin to pick his elk as I have mine in my sights. He said he can’t see through his glass because it’s too frogged up. (His scope rymes with “reapold”) I laugh and take my shot. Drops one elk. I throw him my gun and he takes his. 612m for both. We both filled out tags thanks to the PST Gen 2 and that illuminated reticle.

Rated 5 out of 5 by from PST Gen II 5x25x50 MOA I purchased this scope and installed it on my Savage 6.5 Creedmoor. I constantly shoot 1 MOA or less at 100 yards. My twin brother was so impressed he purchased one to. Both us age 70 and shoot at gun range weekly and recommend you purchase one.

Rated 5 out of 5 by from Go to optic Love this optic. Changes from the gen 1 to the gen 2 were happily welcomed. Especially the turrets. I have this on top of a Remington 700 .308. Sitting in a masterpiece arms chassis. Mostly use it as a target/ training rifle but occasionally will shoot competition and hunt with it. Optic is good all the way around whatever you throw at it. Zero stop locks up tight and back to correct position every time. A lot of bang for your buck.

Rated 5 out of 5 by from I love vortex scopes. I replaced the gen 1 6-24 viper ffp pst with the gen 2 5-25 ffp viper. I love the clarity, does great in low light conditions. Im so happy im going to replace a few scopes on other rifles with the gen 2 vipers

Rated 4 out of 5 by from Hard to beat for the price. I have shot with this scope for a few months now and am overall pretty impressed. It is tough to find another scope in the price range that offers the magnification range, ffp smart reticle, travel per turret rotation, glass clarity, and field of view. I would say the glass clarity is on par with my Nightforce NXS and the field of view and eye box appear to be better. The only downsides to the optic is I don't like how the zero stop has to be set, and if you tourqe your rings past around 17 inch pounds, you will likely have paralax issues. Nightforce and Leupold scopes for example tourqe down to between 25 and 30 inch pounds depending on the model. This makes me think they are a tougher scope, but you also pay quite a bit more.

Rated 4 out of 5 by from Great Scope for Getting Into Long Range Shooting I bought this scope in October of last year as my first scope specifically for long range shooting. I hadn’t shot much past 300yds ever in my life and this scope made things easy. It was easy to zero and learn all the controls, and the clarity of the image even in low light is incredible. The only reason that I’m not giving the scope a 5 star review is that I cannot get the zero-stop feature to set when zeroing, so when shooting at range I have to be extra cautious if I adjust. That being said, it may be user error on the zero-stop and I love the scope enough that I can usually overlook the faulty zero-stop.

Rated 5 out of 5 by from Vortex buyer for life! Bought this over the sig tango series and can’t be happier. Lifetime warranty first off: on everything (sorry sig, you only warranty your electro-optics for 5 years...). Crystal clear glass. VERY tactile knobs which I love. You can easily pay a lot more for the same quality. Vortex comes through every time.

Rated 5 out of 5 by from Top Class! I’ve gradually replaced most of my optics with Vortex. Quality, value, customer service, and a wide range of product lines keep me coming back to them
