About this item

  • The Viper PST Gen II takes incredible performance and rock solid features to new heights. The 2-10x32 first focal plane riflescope is incredibly versatile and ideal for close to long range scenarios.
  • Users who dial their turrets for drop and wind compensation will appreciate the laser etched turrets, adjustable parallax and the RZR zero stop. A fiber optic rotation indicator ensures you can keep track of your turret position with ease.
  • The reticle offers highly functional, intuitive, and detailed hold points, yet remains uncluttered for optimal viewing and features 10 intensity levels with off positions between each setting.
  • Extra-low dispersion glass increases resolution and color fidelity. XR fully multi-coated lenses increase light transmission. Armortek coatings protect the lenses from scratches, oil, and dirt.
  • O-ring sealed and argon purged, the Viper delivers waterproof and fogproof performance while the single-piece, aircraft-grade aluminum construction provides a durable platform.

Viper PST Gen II 2-10x32 EBR-4 (MOA) Riflescope (PST-2101)

This updated favorite 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.

Dual use for Shooting Tactical / Hunting

primary arms

EBR-4 MOA Reticle

  • Hash-marked reticle using MOA-based subtension lines and floating wind hold dots for ranging, holdover, and windage corrections.
  • First focal plane (FFP) reticles are located near the windage and elevation turrets in front of the image-erecting and magnifying lenses. This style of reticle will visually grow and shrink as you change the magnification. The main advantage of an FFP reticle is that the reticle subtensions used for ranging, holdovers, and wind drift corrections are consistent at all magnifications. The reticle is heavier at higher magnifications and finer at lower magnifications.

Other Features

Optical & Convenience

Glass-etched Reticle: Protected between two layers of glass for optimum durability and reliability.

Illuminated Reticle: Provides precise aiming under low-light conditions.

Radius Bar: Fiber optic turret rotation indicator provides a highly visible and tactile point of reference for turret rotations.

Internal

Precision-Force Spring System: Uses premium components in the erector-spring system to ensure maximum repeatability and ease of adjustment.

Precision-Glide Erector System: Uses premium components in the zoom lens mechanism to ensure smooth magnification changes under the harshest conditions.

Construction

Shockproof: Rugged construction withstands recoil and impact.

Hard Anodized Finish: Highly durable low-glare matte finish helps camouflage the shooter's position.

Tactical-Style Turrets: Exposed turrets provide fast, accurate and easily read elevation and windage adjustments.

***11/12/2019 Update***This will likely be my last data point for this scope. I ended buying another PST Gen II and played musical scopes on my rifles. The 3-15x went on my 223 and I picked up a 5-25x mil/mil with the EBR-7c reticle - which by the way is absolutely phenomenal. I wanted to update my post because in my initial review I noted that the turrets were soft in the first several MOA of elevation and then became solid clicks. In my new Viper PST Gen II 5-25 this is not the case at all... The turrets are super crisp the entire way around and tracking has certainly been accurate as I have tall-target tested both scopes. Clicks are still not Razor HD Gen II quality, but for an optic that was purchased below $1,000 this is probably my favorite item on the market. Still highly recommend!!!***3/23/2019 Update ***I purchased this scope in December of 2017, so I've had it about 15 months and as of yesterday, the rifle that it's been sitting on now has 1,200 rounds of 308 Winchester. I finally decided to run this rifle in a PRS match yesterday and I must say I'm very pleased with the performance. My local club matches go to 600 yards, and I had no problems hitting a small 8-inch plate at 600 with 15x magnification. I was able to read the mirage for wind calls quite well. Dialing firing solutions and hold-overs both worked as expected. The icing on the cake for me was winning a wild card stage where they put a balloon on a string at 600 yards and I was able to pop it.Review:I'm extremely impressed with this scope and will go ever several reasons why you should or shouldn't purchase it along with features, functionality, fit/finish, and application.I currently own a Vortex Razor HD Gen II and have had many other top tier scopes as well, but this particular model has left a great impression. I wanted 3-15x because it allows you to engage close range while 15x is certainly more than enough magnification to connect with targets well past 1000 yards if you do your part. This optic is sitting on an AeroPrecision M5E1 in 308win, which I have set up as a semi-auto precision. I plan to use this rifle for hunting, and medium to longer range target shooting. It's got a 24-inch Criterion Barrel, Larue MBT-2S trigger, and Toolcraft BCG..I was able to zero this scope within 3 shots of getting on paper. Tracking is excellent! You will not be disappointed with the visual appeal of your rifle with a PST Gen II sitting on top. This scope just looks great. I'm using the Seekings 30mm AR HIGH rings to mount it. Be careful, standard high rings may be too low and contact the rail. Note, this comes with a sunshade, lens cloth, and allen wrench.This optic is a first focal plane, which means you can use the reticle to range targets at any magnification, and you can use hold overs at any magnification level. Do you really need this? The answer depends on what you intend to use your rifle for. Personally I prefer first focal plane scopes. Once I find the load that shoots best in my rifle, I chronograph it and get a velocity average over 10-shots. With this information, I can create a drop table using JBM Ballistics or Streylok Pro (or whatever ballistic software your heart desires). When you have your drop card made, you can then quickly refer to it and use the scope's reticle to hold over for the specified firing solution. It's fast, it's accurate, and it works... In PRS matches, this is a MUST HAVE feature. Heck, some of the stages are no elevation dialing, so if you don't have a tactical reticle you are kinda screwed. For hunting, I think this is also very applicable. If you have a 100 yard zero and a deer walks out at 225 yards, you may not have time to range it and dial your elevation knob so a quick hold may be all you get.Illuminated reticle is not bright enough for daytime shooting, but this is a precision scope not a red dot. If you're hunting and the sun is going down the reticle illumination will be perfect to make sure you can keep your crosshairs on your target and take the shot at dusk. Also, unlike the Razor HD series only the cross section of the reticle is illuminated, NOT the dot (which I actually prefer as I'm not going to be holding for wind at night time).The clicks on the elevation turret are an interesting point for me... They're definitely not Razor HD Gen II turrets. An interesting thing about my scope is that when I click through 1-4 MOA, to be honest it's kind of soft. Once I hit that 4 MOA mark the turret all of a sudden becomes very crisp and precise. At the end of the day, it's not a Nightforce, Vortex Razor, or top tier scope so you have to sacrifice a little. I think for a $1,000 scope it's an amazing deal and functions extremely well for a majority of applications. There are revolution indicators however so you don't get lost on your elevation knob. Another fantastic feature is the hard Zero Stop. Setting the zero stop was super easy and the spot where you set it at is where it stops. Unlike other optics there is no over travel past your zero. I actually prefer this over the Razor HD Series.Who is this scope for? If you are a long range hunter, target shooter, PRS competitor, or enthusiast this scope is a great choice. If you have an entry level optic and want a scope that has all the pro level features without breaking the bank, this is your scope. Paired with the Vortex guarantee, you cannot go wrong. Without directly naming them, I find many of the other top optic companies in the market have great optics but simply don't give you what vortex does. First focal plane, clarity, parallax adjustment, tactical reticle, illumination, zero stop, 30mm tube, and a sunshade... let's be honest you simply don't get this type of package for less than $2,000 in the market space today.If you're a 'Zero your rifle 1 inch high at 100 yards' kind of guy, I do NOT recommend this scope. You'd be paying far too much for features that you're not using.

Review:

I'm extremely impressed with this scope and will go ever several reasons why you should or shouldn't purchase it along with features, functionality, fit/finish, and application.

I currently own a Vortex Razor HD Gen II and have had many other top tier scopes as well, but this particular model has left a great impression. I wanted 3-15x because it allows you to engage close range while 15x is certainly more than enough magnification to connect with targets well past 1000 yards if you do your part.

This scope just looks great. I'm using the Seekings 30mm AR HIGH rings to mount it. Be careful, standard high rings may be too low and contact the rail.

5.0 out of 5 stars Sharp and clear at any range!
Reviewed in the United States on October 15, 2019
I just bought this scope a week ago and I am blown away by the quality! Super sharp and clear at any range, the EBC-7C MRAD reticle means I won't have to much clicking up for long range, and all the adjustment are smooth and sharp! Another nice feature is the the off detent between illumination settings. Got a brightness you like? No need to dial thru all the settings to get there from off. One click and you are illuminated. One more click and the reticle is back to black! The Viper is built like a tank and is, in my opinion, a great deal for the feature set and quality offered! My only cons? I would love the have flip caps standard (would pay more not to have to order after the fact) and lack of a way to lock the diopter means electrical tape is your friend. I made a small mark with a blue paint pen that lines up with the 0 mark on the barrel as a back up in case it moves. Not pretty but it's solid and the rubber cup on the Defender covers the tape so I won't get any guff from the other guys on the range :)

P.S. Throw an anti-cant level on it while you are at it and your groups will thank you!
