Quick overview

Sparc II is a second generation Sparc red dot, which is a great entry-level sight for most users. The previous generation didn't sit well within high Vortex Optics standards and they improved it a lot making this Sparc II. The price of both sights is the same, but this one is much tougher, rugged, the lenses are more clear and it got rid of all primary flaws that previous generation model had. Just like any other Vortex Optics product, it comes with a lifetime transferable VIP warranty.

Description of the Vortex Sparc II red dot sight

Made by one of the great optic manufacturers - Vortex Optics, this red dot is one of the best entry-level sights you can purchase. The "Sparc" name stands for “Speed Point Aiming for Rapid Combat“. It pretty much tells you the primary purpose of the sight - quick target acquisition and ease of use in rapid combat.

Sparc II was developed as a second generation Sparc model. Many people had minor issues with the first Sparc model, which resulted in a lot of negative feedback being shared online and Vortex Optics has decided to address those flaws by creating a superior model that fits their high quality standards.

Eventhough the optic is made in China, it doesn't feel anything like you'd expect from a Chinese product, usually associated with lower product quality. Just as additional assurance, Vortex Optics provides their usual transferable lifetime VIP warranty. They promise to replace or repair any damaged or defective products with no questions asked and without caring who sold you the optic. As long as it's an original Vortex Optic - you will be covered under their warranty.

The Vortex Optics Sparc II comes in a small box filled with all kinds of goodies. You will notice that without the sight, there are 2 different mounts, flip-up caps for both ends of the optic, spacer, the usual tools like hex key, torques wrench, screws for the mounts and spacer attachment as well as a standard CR2032 battery, which the sight uses.

Vortex Optics Sparc II Packaging

The different mounts are 18 mm and 37 mm height, which could be extended by an additional 3 mm if you decide to use the spacer. Both mounts are compatible with picatiny or weaver rails on a firearm.

We would recommend using the smaller mount if you're attaching it to a shotgun or handgun, while using the taller mount will provide absolute co-witness on any flat-top AR-15.

The caps that sight comes with are easily detachable and will protect your lenses from intentional or unintentional outside damage sources, while the battery included in the same package is a standard CR2032. The advertised battery life is 300 hours at highest brightnes settings or 5,000 hours on lowest ones. After 12 hours without any interaction with controls, the Vortex Sparc II will shut down by itself.

One of the concerns and negatives of a previous generaction Sparc sight was that the battery compartment couldn't be reached by hand and required a tool to access. Vortex Optics has addressed that and made sure that the new generation optic comes with a battery compartment on the right side of the optic, which can easily be turned by hand. The battery compartment cap is also tethered to the housing, making you certain that it won't be lost.

The Vortex Optics Sparc II red dot projects a 2 MOA diameter red dot with 10 different brightness settings. The settings are also saved and upon each use, meaning that the optic will remember last brightness settings used, continuing to use them next time you turn it on.

You can adjust the brightness settings by using Up and Down arrow keys, which could be found on the left-hand side of the optic. We've noticed that sometimes these buttons could be quite unresponsive and require an unexpectedly high force when pushing them to work properly. Not sure whether this was a small defect on the sight we've tested or it's common for other Sparc II sights as well.

A mounted Sparc II optic is parallax-free, meaning that as long as you've zeroed the sight correctly, red dot will always be on the point of impact, no matter which angle you're looking from. The objective lens also has unlimited eye relief, while the manufacturers recommend mounting it with at least 100 mm (or 4 inch) eye relief.

The previous generation came with a 2x magnifier, which would screw directly to the scope, while this one doesn't have any magnification. Majority of complaints for the original Sparc red dot came because of the magnifier and Vortex Optics decided not to add it to their second generation optics.

On the right side of the scope, right next to battery compartment, you have windage adjustment and on top of the sight you'll be able to find elevation adjustments. Both of these allow for up to 90 MOA adjustments with 1 MOA graduation per click.

The adjustment caps are tethered to the optic using a short steel wire, which is wrapped using black fabric, with the intention of avoiding glare as well as potential damages that it could couse to the outside of housing.

Vortex Optics Sparc II toughness review

Vortex Optics Sparc II is considered to be one of the toughest red dot sights within it's price range. The sight has a one-piece military-grade aluminum body, finished with matte black anodizing. Aluminum body is able to withstand most common stress sources like recoil or high caliber rifles and shotguns, being dropped from shoulder height.

All lens surfaces are multicoated, which is standard for this type of an optic. It is also O-ring sealed, making it completely water-proof and fog-proof. 

The optic was also tested in some intense temperatures (note that we have not tested these temperature claims ourselves). The sight was fully funcational between -4 and +158 degrees in Fahrenheit (or -20 to +70 degrees in Celsius).

The sight comes with the standard Vortex Optics warranty, which is fully transferable and lasts a lifetime. They will replace any damaged or defective part with no additional charges or questions asked about it.
