1. AT3 Tactical ARO: Best MCG Red Dot Sight

Searching for the best red dot sight is a daunting task. With so many choices, how do you decide which sight is right for you?

That’s why I got my hands on the AT3 Tactical ARO.

I mounted it to the top of my rifle and headed off to the gun range. After hundreds of rounds, I felt I had put the scope through its paces and can now offer you the definitive AT3 Tactical Aro review.

This highly-versatile red dot sight can be mounted on ARs, pistols, and even shotguns making it the perfect choice for close and medium range shooting.

What makes it such a great choice?

Keep reading to find out…

Glass Clarity & Reticle

The first thing I noticed was that the glass clarity is incredible. The 1x23mm multi-coated lens is crystal clear and offered me a great side-to-side field of view.

Thanks to its 6 brightness settings, the 3 MOA red dot is very bright and easy to see, even in direct sunlight or in very low-light environments.

This makes target acquisition a painless process. Small game hunters rejoice! This is the perfect optic for quickly sighting in on those speedy targets.

Eye Relief and Eye Box

I love the AT3 Tactical ARO’s unlimited eye relief.

The image is always clear from any distance, so I’m able to stay focused while I’m hunting small game.

Even something like a shotgun with a big kick won’t make you gouge your eye out.


This red dot sight is also highly durable, making it ideal for worry-free hunting.

The aluminum body felt sturdy in my hands and can really take a beating, keeping the internals well-protected.

All the electronics are sealed away in a waterproof casing and the scope is shockproof up to 500g. The matte black finish is scratch resistant and gives the sight a truly tactical look and feel.

The AT3 is also nitrogen-purged to eliminate moisture inside the scope and keep the lens from fogging up due to changes in temperature or humidity.

Overall, the AT2 is incredibly durable optic and won’t fail you when you need it most.

Elevation & Windage Knobs

Reliability might be the single most defining feature of the AT3 Tactical ARO, and the turrets are no different.

I loved the feel of the windage and elevation knobs. They give off a satisfying click, and adjust at 1 MOA per click.

Zeroing in on a target is a breeze, and the sight holds zero very well, even after the hundreds of rounds I fired with it.

Parallax & Magnification

Because the sight is designed for close to medium range shooting, it offers no magnification.

But I’m not looking for magnification in a red dot. Also, like all red dots, the AT2 Tactical is completely parallax free.

Mounting & Rings

Mounting the scope to my gun was relatively simple.

Out of the box, it comes with a Fastfire/Venom Style Mounting Footprint and includes a removable Low Mount for Picatinny Rails.

This is a great configuration for pistols.

The AT3 is also compatible with an absolute co witness riser mount for the Tactical ARO.

  • ABSOLUTE COWITNESS - Best for using Micro Red Dots on Modern Sporting Platforms - Also compatible with Vortex Venom and Burris Fastfire Red Dot Sights
  • CANTILEVER DESIGN - The angled, single-rail mount keeps the red dot forward for fast target acquisition
  • LIGHT WEIGHT - At only 1.1 oz, this is one of the lightest red dot risers out there!

If you plan to equip it to an AR, I would really recommend you opt for the riser mount like I did. T

The extra height it provides makes for more comfortable shooting and sits the scope at the perfect height to be used in conjunction with other optics.

Is the AT3 Tactical ARO Worth it?

The AT3 Tactical ARO is an incredibly versatile short and mid-range optic. I found it to be absolutely worth every penny. It really ticks all the boxes and has all the features I expect from a top-of-the-line sight, including:

  • Affordable price
  • Lifetime Warranty
  • Unlimited eye relief
  • Truly incredible durability
  • Additional mounting option
  • Very clear multi-coated lens

So if you’re looking for a quality, versatile red dot but don’t want to break the bank, the AT3 Tactical ARO is the red dot for you.

2. Feyachi RS-30: Best Reflex Sight Under $50

The Feyachi RS-30 40mm is the best budget (under $50) red dot reflex sight for your AR 15.

In fact:

It’s my favorite sight for hunting. I even install it alongside my primary long-range scope on my riflescope. So I don’t miss near-moving targets.

Interesting isn’t it?

To know more read on…

Glass Clarity & Reticle

The Feyachi RS-30 offers crisp clearness. Thanks to its AR (anti-reflective) coating which helps to prevent excess light from entering my eyes.

This crucial feature is the reason why I hardly miss my first shot. Even if I do miss, I still find it easy to reacquire my targets.

This $50 40mm tubeless sight has a wide field of view. Great for complete situational awareness. Especially against fast-moving close range (within 100 yards) targets.

To top it all up, the Feyachi RS-30 can be illuminated within 5 brightness settings. Via a button instead of a knob. With this feature I can shoot all-day (both in low lighting and full sunlight) with confidence.

Also, the Feyachi RS-30 offers 4 reticle patterns to choose from. All to meet every possible need!

Reticle options include crosshairs, reddot, dot-in-ring, and crosshairs-in-ring.

The only con with the sight is the crosshairs reticle. Which is not straight.

Dot & dot-in-ring reticles are great alternatives.

Eye Relief

Feyachi RS-30 provides unlimited eye relief. This means I don’t have to worry about hurting my eyes while I take my shot. I also get to open both eyes while using this reflex sight.

The only downside to using a Feyachi RS-30 sight is the inability to zoom in on targets. Because it’s a reflex sight.

Build Quality

I don’t like heavy and bulky sights because they’re weight & complicated. Which is why I go with the Feyachi RS-30.

It’s light-weight because it’s made from high-grade aluminum. So there’ll be less friction between the rifle and the sight. And it’s easier to install.

The Feyachi build is also durable (shock-proof). Durable enough to withstand impact of a few feet, which is great for preventing a cracked lens.

And finally, its design is tidy.

Take a look at the battery compartment. It’s right below the front of the sight. Very easy to access. I don’t need to extract the sight from my rifle or lose my zero. All because I want to change the battery.

It saves a lot of time!

Speaking of batteries…

Battery Life

This may not be the Trijicon sight (battery-free sight) but it can last for a long time.

Hypothetically, if the sight is used continuously at low capacity then it should last for up to 5 years. That’s an estimated 50,000 hours worth of battery life. You won’t even notice depletion.

This reflex sight also features an auto-off after 1 hour of no use. That means more battery power is being saved. Probably without notice as well.

Elevation & Windage Knobs

Knobs/turrets on this sight are 100% reliable.

This is so because for every adjustment made there’s a crisp click sound that follows. Such adjustments are done via a hex Allen wrench (two available).

Zeroing this piece is easy. It measures at 2 MOA increment which works fine for the AR platform. If you can, get a professional gunsmith to do it.

If perfectly zeroed, the sight should be able to hold (it’s zero) after about 200 rounds (AR platforms including AR 12 shotgun). It also holds well with a .223.

The downside about the Feyachi’s turret is that you need to loosen the locking screw. Just to make changes to elevation or windage.


For a budget sight under $50, you shouldn’t be surprised with parallax. It’s even the kind that’s forgivable.

Unless one suffers from astigmatism. Then I suggest getting your glasses on.


This sight comes pre-mounted to a secured 20mm Picatinny rail mount. That easily fits into a Picatinny or Weaver rail. Thus making it compatible with most AR rifles.

I recommend the Picatinny because it’s a single piece. And it’s Rail’s slot or groove is deeper and wider than the Weaver double piece mount. There it’s a lot easier to install and remove.

Recommended Accessory: don’t rely on the default alkaline batteries. AG13 or LR44 batteries should be considered. Or better yet, a Lithium-ion battery is ideal for saving money.

Is the Feyachi RS-30 worth it?

If you’re looking to spend cheap on an optic that’s a fraction of most EOTech Sights. Both in terms of price and weight. Then the Feyachi RS-30 is for you.

3. Bushnell Trophy TRS-25: Best Red Dot under $100

What if I told you there was a red dot that is clear, durable and reliable…for under 100 bucks.

Would you believe me?

Probably not.

But there actually is one, and it’s called the Bushnell TRS-25. Let’s take a closer look…

Glass Clarity & Reticle

When I bought my first TRS-25, I thought: “such a low price must mean low glass quality.”

Man was I wrong.

The glass is incredibly clear with only a minimal tint, with perfect red-dot visibility throughout. The high quality, multicoated, Amber-Bright high contrast lens cuts out glare, and thanks to the nitrogen inside the scope, I never have to worry about fogging under any conditions.

This is the perfect scope for hunting or shooting up to 300 yards.

The simple red dot reticle has three MOA settings and it’s great for any pistol, shotgun, or a low to mid-range rifle.

If you don’t need to focus on precise measurements of distance, or distant targets that require measuring bullet drop, you won’t need anything fancy.

Sure, it’s no Aimpoint, but when was the last time you needed an over-sophisticated tactical reticle, for the range or to hunt deer?

And it’s simple and easy to use — my 15-year-old nephew loves it. It’s also easy to see; my dad has no issues anymore hitting targets, and doesn’t even need to take off his glasses.

It’s great for eyes that don’t see like they used to.

Eye Relief & Eye Box

The TRS-25 has unlimited eye relief, regardless of how much kick your gun gives you.

And from inches to feet away my target always looks the same. I can even use both eyes with no trouble. I have one mounted on my rifle, my AR pistol and my shotgun, and still have unlimited eye relief on all of them.

I can even mount the scope close to the rear end and still have no fear of eye injury. .


Remember my 15-year-old nephew? Well this scope can even survive him.

He’s dropped it a few times since I gave it to him, on the concrete patio too. It still zeros like it never happened. The housing is also metal and does a good job protecting the sight.

The compact and high quality construction of the TRS-25 leads to high durability. It can take tons of abuse and will still work in any rough environment, any situation.

Elevation & Windage Knobs

The turrets click nice and loud and the elevation is perfect.

I’ve tried out each one I’ve bought as soon as I get them, turn the elevation to max and aim. They’ve zeroed, and held zero dead-on each time.

The turrets don’t have any real special features and they don’t wind as smoothly as butter. But like I’ve said it’s no Airpoint (and certainly doesn’t coast over $400 like an Airpoint either) but the TRS-25 always tracks true.

Since I don’t really do any tactical shooting, this isn’t a problem. And for the price I still can’t complain.

Parallax & Magnification

There’s no magnification with this scope, it’s 1x.

But I certainly don’t need any magnification for any targeting under 300 yards. I also use mid-range rifles and have no real need to magnify anyway.

Besides, no magnification means no parallax, at all, ever.

Mounting & Rings

There’s no mounting included with the scope. But I have guns with both cross-bolt and picatinny mounts and I’ve never had any issues.

I wouldn’t waste any money on accessories either. The rubber scope cover it comes with works just fine. Also I’ve never bothered with a lens shade because this scope works perfectly in any lighting conditions.

Is the Bushnell TRS-25 worth it?

Yes. For around 80 bucks, it doesn’t get much better than this.

Sure, there are better optics like the Aimpoint Pro, but keep in mind it’s 4-5x the cost of the TRS-25.

Besides, unless you’re about to gear-up and jump into hostile territory, or live-out scenes from Rambo III, you’re not going to need a sophisticated and expensive scope. The Bushnell Trophy TRS-25 Riflescope is good for everything I need.

4. CVLIFE 1X22X33: Best for the Budget

The CVLIFE 1x22x33 is a perfect no-frill reflex sight.

In fact, I’d argue it’s one of the best for the budget. Here’s why…

Glass Clarity & Reticle

The CVLIFE’s 1x22x33 reflex sight is perfect for learning what you want in a sight.

It has 5 red and 5 green reticle brightness settings, and has 4 reticle options. I like the green option, and tend to use it on the second dimmest setting. I also go for the small dot reticle, the other reticles are purely aesthetics and only cover FOV, in my opinion.

There are some QC issues with glass mounting. However, that’s the risk you take when you try to go cheap. The glare protection isn’t great, and changing the reticle settings (including brightness) can throw off the zero.

These cons are pretty easily mitigated by choosing a good spot to shoot from, and deciding which reticle settings you like the most before you zero.

Eye Relief & Eye Box

Being a reflex sight, eye relief is no issue and the eye box is nicely sized. It allows a pretty large range of motion to either side before you come into accuracy issues.


This is where the sight loses a lot of ground.

It’s a cheap sight. It’s made of aluminum and rubber. Your results WILL vary. Some people shoot a thousand AR-15 rounds with this sight and notice nothing, or your glass could fall off while you’re mounting.

Glass mounting on this sight appears to be the weakest link in most cases. This is by far the largest con of the scope.

Elevation & Windage Knobs

The turrets on this sight were very adequate.

They were surprisingly consistent moving back and forth. The clicks sounded nice, but the action is slightly mushy. While the scale isn’t all you dreamed of, it’s perfectly adequate for reflex sight applications.

Zeroing is pretty easy. As far as I can tell, the zero holds pretty well.

Parallax & Magnification

This scope doesn’t have any magnification, but that’s kind of the point.

It’s a short range optic — anything above a 1.5x is going to be more bad than good.

As with all reflex sights the parallax is near nonexistent. You really gotta create some monster of a situation to have meaningful parallax on a reflex sight.

Mounting & Rings

This scope mounts to just about any top rail. Sadly, it won’t fit your fancy RMR cutout. It uses allen key screws to mount to the rail. A key is included.

Is the CVLIFE 1x22x33 worth it?

Absolutely, especially for lower power guns.

However most, but definitely not all, will stand up just fine on a more powerful gun like an AR-15. Buy the CVLIFE 1x22x33 reflex sight if you’re one of the following people:

  1. You just bought your first pistol or rifle for short distance shooting
  2. You own 10 rifles and are sick of swapping scopes
  3. Or you’re broke

Regardless of your reason, at $30 (pre-corona as low as $17) you cannot go wrong. You bought it and it turns out QC really didn’t do their job? Just buy another, you’ll still be ahead.

While manufacturing defects make up a small amount of these shipped scopes, it’s definitely a much larger proportion than more expensive companies (and good luck getting a response from customer service).

But if your sight lasts the first few shots, you’re going to be VERY happy with your purchase.
