The SPR Idea
Vortex releases a brand new light-weight 2-10x as mid-power scopes proceed to develop in reputation.
I’ve been dabbling with the Particular Goal Rifle (SPR) idea for the final yr or so and I’ve discovered an actual appreciation for the practicality of a superb SPR setup. That is the second scope I’ve used that matches the class with the primary being Major Arms GLX 2.5-10.
In broad phrases, an SPR is simply an AR constructed with mid to long-range use in thoughts. Distinction this with a Quick Barreled Rifle (SBR) which is supposed for brief vary and a Basic Goal Rifle (GPR) that tries to do some of the whole lot. Beneath you will notice a graphic depicting the connection I see between these three rifle sorts.
Whereas I do have a devoted SPR construct, I made a decision to swap the 1-8x LPVO on my 14.5” GPR for the Vortex Viper HD 2-10. I wished to see how the 14.5” would profit from a bit extra magnification. Whereas 14.5” is a bit shorter than the everyday SPR, I feel it suits the function effectively sufficient since my purpose is elevated precision inside 5 hundred yards.

Viper HD 2-10 Specs
To start out, listed below are the overall specs.
42mm goal lens Second focal aircraft Capped turrets Fastened 100yd parallax Discipline of view is 61.6ft-11.9ft at 100yds 3.4in eye reduction 12.1in lengthy 19.9oz in weight 30mm predominant physique
A 12.1” size is fairly commonplace for a scope with this magnification vary however the 30mm tube, not a lot. The bigger tube is a pleasant characteristic because it aids gentle transmission and permits for extra elevation adjustment than a 1” tube nevertheless it provides a little bit of weight. Not an excessive amount of on this case although as a result of an total weight of 19.9oz is on the lighter finish of its class.
Viper HD Parallax
One other fascinating design alternative is to have a set 100-yard parallax. Parallax is the distinction within the obvious place of an object when seen from two positions. A easy demonstration of that is to shut one eye and place your thumb over a goal a number of yards away. Then, holding the thumb nonetheless, transfer your head backward and forward and observe how the thumb seems to maneuver relative to the goal. Subsequent, bodily place your thumb on the goal and transfer your head once more. The thumb doesn’t transfer as a result of the gap between the goal and the thumb is zero.
On this train, your thumb represents the reticle, and the gap between the thumb and the goal is the distinction between your parallax setting and the precise distance. A appropriately adjusted parallax optically corrects for the gap between the reticle and the goal making it behave as if the reticle is correct on prime of the goal. This minimizes the results of imperfect head placement and will increase reticle readability.
Excluding the flexibility to regulate parallax simplifies the optic because it deletes an adjustment nevertheless it requires the shooter to follow constant head placement or else pay the value with attainable inches of parallax error at lengthy vary. Because of this, I desire adjustable parallax vs fastened.
Useless-Maintain BDC Reticle
The Viper HD incorporates a easy and clear reticle. See the MOA spacing of the Useless-Maintain BDC reticle within the graphic beneath.
One issue that shouldn’t be neglected is that this can be a second focal aircraft scope. That signifies that the reticle stays the identical dimension on all of the magnification settings. In case you plan to make use of the hash marks within the reticle for holdovers you want to pay attention to what magnification you might be on. As a common rule, most individuals solely use reticle BDC on max energy with a primary focal aircraft scope because the angular deviation between the markings will probably be completely different for each magnification.
Reticle Illumination
This reticle options an illuminated dot on the heart of the crosshairs. You flip it on by urgent the button reverse the windage turret. There are 9 brightness settings on the Viper HD that you just scroll by means of by tapping the identical button. If you attain the best or lowest brightness degree the dot will flash letting you could have maxed out in that route. Merely maintain the button all the way down to shut off the illumination.
Moreover, there may be an auto-off characteristic on the illumination. In contrast to a pink dot with a battery that may final for years, illuminated scope batteries typically drain inside a few days if left on. As my dwindling battery provide can attest, I neglect to show them off far too steadily. Within the case of this scope, I’ve left it on a number of occasions and are available again days later to seek out it has shut itself off saving me a battery substitute.
This reticle illumination is one among my favourite elements of the scope. The activation button is a lot slimmer than the rotating turret most scopes use. The illumination level within the heart is vivid sufficient for use like a pink dot when the scope is on low magnification and it does a superb job of driving your focus to the middle of the reticle.
Windage and Elevation On the Viper HD
Knurled aluminum caps cowl each the windage and elevation turrets. You can see that the laser-engraved turrets are sturdy and simply adjustable by hand. Changes are easy however tactile and every quarter-inch adjustment is indicated. To set zero place merely pull the turret out, transfer it to zero, and let it lock again into place. With the zero place set, you may confidently dial windage and elevation changes with out dropping your zero.
Readability and Discipline of View
This scope presents good readability and produces a vivid picture even within the early morning or late night. That is notably good when attempting to utilize these previous few minutes after sundown and in overcast situations.
The sector of view is good and broad. I’ve a superb broad view of my goal’s environment when utilizing this scope versus many others the place it seems like I’m trying by means of a paper towel roll.
There’s a little bit of picture distortion close to the sting however I might fairly have a little bit of distortion across the perimeter than a narrower picture with edge-to-edge sharpness.
Last Ideas On the Viper HD
General I feel this can be a good scope and I’ve discovered that the extra I exploit it the extra I prefer it. I used to be proper to assume it might make a superb SPR scope and just lately I’ve began to see its worth as a searching optic as effectively.
The capped turrets, light-weight design, and good gentle transmission are all wonderful options for a searching scope. Even the shortage of parallax adjustment turns into a nonissue when searching medium to massive sport inside 5 hundred yards.
