Bottom Line Up Front

Updated for 2020 the Vortex Crossfire Red Dot Generation 2 comes with a substantial increase in battery life. All while maintaining a reasonable price point for a quality red dot sight.

The sight maintains all of its previous features and what I would call one minor annoyance. Continued quality and excellent warranty make the Vortex Crossfire red dot sight an excellent optic in this class.

Vortex Crossfire Red Dot Review

In my opinion Vortex Optics continues to meet its customer’s expectations to deliver quality optics for shooters of all types. The Crossfire Red Dot Sight in its generation 2 update is a great example of Vortex’s commitment to its customers. The Crossfire Red Dot is suitable for beginning to expert shooters for all platforms.

Even though this red dot optic has been spotted on all manner of firearms, from pistols to shotguns, rifles, and even crossbows, it really has become an all-time favorite for AR-style platforms connoisseurs.  

Crossfire Gen 2 Top Features


The sight is constructed out of aluminum for a tough and lightweight frame that has proven tough under various environmental conditions and shooting scenarios.

The overall length of the Crossfire is 2.5 inches with 1.1 inch diameter objective and ocular lens. The weight of the sight is 5.2 oz.

This optic has a durable anodized low glare matte finish and nitrogen purged o-ring sealed chassis that provides moisture, dust, and debris resistant operation.

I have yet to find the Ingress Protection (IP) rating for this site, but according to the manufacture, the optic is waterproof.


The Vortex Crossfire red dot sight comes in a single reticle option, sporting a 2 MOA (Minute of Angle) LED illuminated red dot.

It has been my experience that the smaller the reticle size the better. It allows for more accurate placement of rounds as well as excellent target identification/acquisition, especially at increased distances.

There are 11 reticle brightness settings. Eight of the settings are for daylight conditions with the remaining lowest 2 settings reserved as night vision compatible options.

You will find the brightness setting range of the Crossfire sufficient for all light conditions and backgrounds encountered by most shooters.

Illumination brightness is controlled through a large dial on the right side of the sight. The dial provides just the right amount of tactile distinction between settings. The night vision settings are labeled N1 and N2 on the dial.


Vortex Optics designed the Crossfire RDS for simplistic straight forward operation. The sight features a single dial to turn the reticle on/off and set the brightness.

Remember the one minor annoyance I mentioned above?

It is the fact that the reticle brightness dial stops at its extreme settings requiring you to move it all the way in the opposite direction instead of continuing on in the same direction.

The sight has two point of impact adjustment knobs . The elevation adjustment knob is located on the top of the optic while the windage adjustment knob is located on the right side.

Adjusting the elevation or windage by one click will move the point of impact by 1 MOA or one inch at 100 yds. The adjustment knobs provide both a tactile and audible click and are protected by screw on turrets.

The Vortex Optics Crossfire Red Dot Gen 2 utilizes a CR 2032 3 volt lithium coin battery providing 50,000 hrs of operation while on the level 6 reticle brightness setting.

The battery is side mounted within the reticle brightness dial making access and battery changes a snap.


The Crossfire Red Dot Sight comes with two mounting height options out right out of the box.

The sight includes a low height mount and a lower 1/3 co-witness mount both of which require your firearm to be equipped with a Picatinny or Weaver-style rail/base.

Tighting of the base clamp bolts are achieved with the provided hex wrench.

Vortex Optic VIP Warranty

According to Vortex Optics, the will “repair or replace your Vortex product in the event it becomes damaged or defective—at no charge to you.” And if they can repair the product they will replace it.

The VIP warranty is good for all red dot sights and carries a Unlimited Lifetime Warranty that is fully transferable, no receipt needed.

Now I have never had to use the warranty so I searched high and low for customers who were disappointed with the warranty. And to my surprise, almost everyone praised the customer service and the warranty.
