Sparc Ar Gen 1 Vs Gen 2- A Detailed Comparison Guide


Sparc Ar Gen 1 and Gen 2 are optic sights developed by vortex and which seem to be in competition with each other; the Gen 2 as we are about to find out is supposedly a better version of Gen 1.

You will, therefore, realize that Gen 2 is more sleek and slim when compared to Gen 1 in that it is less bulky and has shed off the external control features that seem to be protruding from gen 1. Gen 1 also comes with a detachable riser, meaning you can remove or put it back as you deem fit, Gen II on the other hand, comes attached to its riser thus inseparable.

The structural differences in the two sights are quite many all of which are meant to enhance performance, given that the Gen 11 is a more advanced version let us find out what it has to offer, hunter, and range shooters.

Build and Design

At 7.5oz the Sparc Ar Gen 2 allows users to set the sight in their most favorable height, for the above you have been provided with a spacer, a low, and a high mount. Spark two is also bulkier given that the controls and the battery have been incorporated on the sides of the unit. Gen 1 on the other hand, is compact with the controls and battery shifted at the bottom front and back part of the sight; you will also realize that the battery has been changed from the coin-like design to a triple-A thus more effective.

Gen1 is also equipped with flip caps used to cover the lens a feature that is significantly missing in Gen 2, the latter on the other hand, is equipped with the windage adjustment used to impact the horizontal direction of the bullet and the elevation adjustment for customizing the height of the optic sight.

Overall Gen one has the best build and design because it is a bit slimmer and sleek, and the intuitive controls have been placed within the reach of the shooter.

Optical performance

Both the Sparc Ar 1 and Gen 2 offer impressive optical performance, for one they provide increased light transmission, thanks to the multiple anti-reflective coatings. And when using any of these sights in the range, eye placement is not all-important as all you need to ensure is that you can see the dot, which will then make target acquisition easy.

You will also experience zero fogging, nor will the sights admit dust debris from the surrounding environment. There is, however, a slight difference in the illumination settings because for Gen 2 you will get up to 12, which will allow you to change the dot intensity with regards to your environment and the situation at hand. Gen 1 only gives you 10 illumination settings, and cannot be submerged into water.

The above then make the Sparc Ar Gen 2 optics the better units simply because it has more illumination setting and can be used when submerged into water up to 20m.

Battery life

The Sparc Ar Gen 1 and Gen II offer impressive battery performance but you will realize that their orientation and design are quite different. For example, Gen 1’s battery is the easiest to access given its location at the base of the sight’s lens, and it is a triple-A battery that can be sourced from most of the convenience stores.  Gen II, on the other hand, is equipped with a coin-like battery, placed at the side of the sight, and while it might be easy to access replacing it can eat up your time.

The battery life of both sights is also a matter of concern given that Gen 1 offers more hours during use while Gen II seems to be underperforming by offering fewer uptime hours. Gen 1 is, therefore, the better unit, one because the placement of the battery allows easy access, the battery is easily available and offers more uptime hours when compared to its counterpart.

Construction Quality

As usual, Vortex always seeks to offer the best when it comes to optics, but for the Gen 1, we must say that the construction quality is not at its best, first because it does not fare well in moist environments, and for as much as the construction quality is waterproof, the unit is not water-resistant. Gen 2 which comes out as the best sight overall does feature quite a sturdy build for the price and will be at its best when deployed in most environments.
