Preface
Apex Optics is a relatively new manufacturer in the optics market, with their roots planted firmly in the mountains of Alberta Canada the company has aggressively pursued the firearms market worldwide. I was introduced to Apex Optics with their Rival precision rifle scope, and I’ve been shooting with it for about a year now. Having experienced great performance from their product, I embraced the opportunity to try another. Today I bring you my impression of the Apex Optics Atom red dot, a compact reflex sight.
The Apex Optics Atom
The RMR footprint is a very popular style, and the Atom utilizes this footprint for its universally accepted popularity. Using a battery to power it’s Smart-Light auto adjust reticle for up to 50,000 hours. With a structure made from aluminium, the light and robust Atom is made to last. Incorporating as much technology as possible was done by adding their 7-layer lens coating as well as incorporating motion sensing electronics to power up the unit with any activity.

Whats in the Box
In the box comers the Atom red dot, as well as a picatinny rail mount should you chose to mount it to a carbine or other type of weapon. There also came three different screw sets to help you with options for mounting on different firearms. There also came the typical literature and lens cloth, the manual came with a great deal of information on how to configure, adjust and mount the Atom. And of course it came with a custom tool that helps get the right fit to both mount and adjust the Atom. In addition to whats included, the Atom also has the ability to install a hood (available separately) that encloses the red dot. Protecting it from dirt and debris.

Installing the Atom red dot
I decided to install the Atom on my BCA Grizzly, a Glock 17 clone with a slide cut for the RMR footprint. This would make it easy, and using the provided screws and a couple drops of blue Loctite it was done quickly. When mounting red dots I always try and ensure as I bolt them down to the slide that they are as close to lining up with the iron sights as possible. This practice reduces the need to adjust the reticle much after install.
On the Range
Once I’d done that, it was time to head to my shooting spot to test them. With quite a few boxes of Trailforger 9mm ammo, I wanted to have good time while testing this little dot. The first thing I had to decide was how I wanted to configure the reticle. The MRX reticle is a circle dot style reticle, you can select between the 2MOA dot alone, the 34MOA circle alone, or the two features together if you like. I ended up mostly using the circle, its small enough that I would basically just bracket whatever it was I wanted to hit and squeeze the trigger. More precise shooting could be done using the 2MOA dot.

Adjusting the reticle and brightness is all done using the two buttons on the left side of the Atom. As well as set the Smart-Light feature. The lowest two settings are designed for night vision use, which is pretty typical. I also noted that the manual mentioned something I see on most red dots, it is recommended to not use the dot on the highest brightness settings unless it is warranted. The highest brightness settings often cause a glare and whats called “reticle blooming”. Reticle blooming is when the reticle becomes so bright that it looses it definition and makes aiming harder. This affects all red dots in my experience, which I usually use on the lowest setting that is clearly visible while shooting.

The Atom was very nice to shoot with. The brightness was more than enough for midday shooting, and it allowed me to accurately hit my targets. I have recently gotten used to the extra-large window of some other red dots, so it took a minute to get used to the slightly smaller window of the Atom. Once I’d familiarized myself with it though, I really liked the less obtrusive window size. I feel like I’d like to put this on my CCW pistol for confident shooting.

While the lower housing of the Atom was a touch too thick to allow the use of my iron sights, I was still able to use them by using the “look through” method. Basically pretending the obstructed front sight isn’t obstructed 😅. These sights are pretty low profile, so any slightly taller sights would be useable through the Atom red dot.
The significant travel of the reticle mechanism in the Atom is very nice, should you need to make big adjustments to zero. Luckily I didn’t for this purpose, but I was happy to see there was so much adjustment available as other red dots I have only offer a third of the movement range.

Pros and Cons
Lets talk about the pros and cons of the Atom. First of all, keep in mind that I am used to quite a variety of different red dots.
I like the size of the Atom for the RMR footprint, I like that it has a rounded top with fewer corners to snag on things. Despite being smaller than many of my other red dot windows, I still feel like it is big enough to be very useful.

The reticle options is where it really shines, as we all love having options. I like that you can select the various circle or dot options, and the motion activation and auto-brightness are a fantastic options to have.
The fit and finish of the Atom is outstanding. The tight fit of all the parts and fasteners make for a very professional presentation. As do the packaging and included accessories.
If I had to change something on the Atom it would probably be this; I like the reticle options, but I wish there was like a 40, 50, or 60 MOA option as well. I am ready to accept that this is simply my personal preference though. I wish I’d gotten one of the Weather Shield hoods for the optic as well, to see how it works and if it inhibits function at all.

While I have no reason to suspect any failure, I was surprised that the battery compartment is secured only by a friction detent. Part of me wants to think a screw or other mechanical method of securing would be better. But in all my shooting, I cannot think of a scenario where it could be knocked out. So I think its fair to say my concern is misplaced.

Last Words
Much like my previous experience with Apex Optics, the Atom has left me with a great impression. There are so many options out there for red dots these days, so standing out from the crowd is a challenge. I think the Atom offers some great features, there are others that offer similar performance for less, but they don’t stack up as well. And those who’s features exceed these, are priced above and even well beyond what the Atom costs.
While I like my dollars to stay in America, I’d rather send them to Canada than China or some other sweat shop. Especially when there are better options like these made in Japan where there is a higher quality standard. If you find yourself looking at the Apex Optics Atom red dot, I think you will enjoy shooting with it and feel satisfied with your purchase.
