Alright, let’s get into it. The Trijicon MRO is something else, folks. This Red Dot Sight offers a 2 MOA red dot, which makes for easy target acquisition and precise aiming. 

You can easily adjust the brightness to suit your needs, whether you’re in broad daylight or dim conditions. And did I mention it’s waterproof up to 100 feet? Yep, you heard that right. It’s also got this ambidextrous switch that’s super handy. All wrapped up in a solid aluminum housing for durability.

Why To Buy 

Now, why should you invest in the Trijicon MRO? First off, this thing is built like a tank but without the weight—only 2 ounces! The brightness settings are versatile, and the red dot is crisp and clear, which is vital for accurate shots. 

The 50,000-hour battery life means you don’t have to stress about it dying on you. And let’s not forget, it’s waterproof. 

Whether you’re in the rain or accidentally drop it in water, it’s got your back. Plus, easy adjustments mean you won’t fumble around when it matters most.

Why Not To Buy 

Okay, let’s talk downsides. One glaring issue with the Trijicon MRO is the price. It’s not cheap. So, if you’re on a budget, this might be a tough pill to swallow.

Who Should Buy 

So, who’s this for? If you’re a serious shooter who doesn’t want to compromise on quality and performance, the Trijicon MRO is for you. Its durability and precision make it ideal for law enforcement, military personnel, or even dedicated hobbyists. 

If you’re someone who’s already familiar with Red Dot Sights and wants to upgrade, this is the next logical step. It’s also for those who require a versatile sight that can handle different environmental conditions.

My Testing 

Now, how did it fare on the Kel Tec Sub 2000? In a word, awesome. I tested it in various light conditions, and it performed consistently well. 

The red dot helped me achieve rapid target acquisition, and its lightweight design didn’t unbalance the gun. 

The sight remained steadfast, whether I was firing single shots or bursts. Honestly, it felt like the Trijicon MRO and Kel Tec Sub 2000 were made for each other.


  • Durable aluminum housing
  • Crisp 2 MOA red dot
  • Versatile brightness settings
  • 50,000-hour battery life
  • Waterproof up to 100 feet


  • Pricey
  • Initial setup can be tricky for beginners

2. Holosun 510C – Runner Up

Let’s dive into the HOLOSUN HS510C. This Red Dot Sight comes with a 2 MOA red dot and a 65 MOA open circle, giving you options to fit your shooting style. 

The automatic brightness feature is a game-changer. Trust me, it adjusts to your environment, so you don’t have to. It’s also got a solar failsafe and a “shake awake” feature, making sure it’s ready when you are. 

Weighing in at 8.3 ounces, it’s a bit on the heavier side but still manageable.

Why To Buy 

So, what makes the HOLOSUN HS510C worth your hard-earned money? It’s packed with top-notch features, for starters. 

The multiple reticle options give you customization that you just don’t see every day. The automatic brightness adjustment is spot-on and takes the guesswork out of the equation. And let’s talk battery life: 50,000 hours. 

Why Not To Buy 

Alright, nothing’s perfect. The HOLOSUN HS510C doesn’t come with night vision compatibility. Also, weighing 8.3 ounces it can add a bit of heft to your setup. 

So, if you’re looking for something ultra-light, this might not be your best bet. Lastly, while it’s IPX-7 waterproof, it’s not the toughest out there when it comes to water resistance. 

If you’re someone who demands those particular features, you might want to keep looking.

Who Should Buy 

So, who’s this sight best for? If you value adaptability and innovation, the HOLOSUN HS510C is your guy. The multiple reticle options and automatic brightness adjustment are just too good to pass up. 

It’s excellent for both pros and weekend warriors who don’t want to compromise on features. Those with visual challenges like astigmatism will find the reticle options a godsend. 

The durable build and long battery life make it perfect for those who need a reliable, long-term investment.

My Testing 

I paired this beauty with my Kel Tec Sub 2000, and boy, was it a match. The sight was easy to mount, and those multiple reticle options were fantastic for various shooting tasks. 

I found the “shake awake” feature particularly useful during rapid transitions. Although it added a little weight to my gun, it was totally worth it for its features and durability. Thumbs up from me!


  • Multiple reticle options
  • Solar failsafe technology
  • 50,000-hour battery life
  • “Shake awake” feature
  • IPX-7 waterproof


  • No night vision
  • Slightly heavier

3. Bushnell Trophy TRS 25 – Best for Beginners

Meet the Bushnell Trophy TRS-25, the go-to for beginners. With a 3 MOA red dot, it’s simple but efficient for acquiring targets. 

You can tweak the brightness levels to match your surroundings, which is pretty useful. At 0.23 pounds, it’s lightweight. A neat feature is its nitrogen-purged technology, making it resilient in various weather conditions. 

Battery life? It is around 3000 hours, not endless, but it’ll do the job for someone just starting. It’s got O-ring seal protection, adding to its durability.

Why To Buy 

So, why should you consider the Bushnell Trophy TRS-25? First off, it’s a beginner’s dream. 

The 3 MOA dot is crisp and clear, great for target acquisition. Adjusting brightness levels? Easy peasy. Plus, its nitrogen-purged technology is fantastic for battling against humidity and temperature changes. 

If you’re a newbie, you can get to grips with this sight without any fuss. I

Why Not To Buy 

Time for some real talk. If you’re an experienced shooter or have military needs, you may find the 3000-hour battery life a bit lacking. 

Also, the sight doesn’t offer some of the advanced features you may want as you level up your skills. Sure, it’s versatile, but it’s not exactly feature-rich. 

It doesn’t have the bells and whistles like solar backup or multiple reticle options. So, if you’re in the market for something a bit more advanced, maybe keep shopping.

Who Should Buy 

This sight is tailor-made for beginners or those on a budget. The Bushnell Trophy TRS-25 provides just what you need without overwhelming you with features you might not use. Its simplicity is its charm. 

If you’re new to the world of firearms and Red Dot Sights, this is your entry ticket. And if you’re worried about environmental conditions, the nitrogen-purged tech has got you covered.

My Testing 

I slapped this sight on my Kel Tec Sub 2000 and took it for a spin. First thing, it was easy to install; there was no rocket science there. I found the 3 MOA dot crisp and effective for different shooting distances. 

The sight held zero well, but the battery life was as advertised—good but not great. Still, it performed admirably and didn’t disappoint in the durability department. It’s a solid choice for beginners, I’d say.


  • O-ring seal protection
  • Nitrogen-purged tech
  • Versatile illumination settings
  • Bright, crisp 3 MOA dot
  • Shockproof


  • 3000-hour battery life
  • Limited advanced features

4. Vortex Crossfire – Best Value for Money

Say hello to Vortex Optics Crossfire Gen II, the sight that offers bang for your buck. Sporting a 2 MOA red dot, this bad boy offers precision at a distance. 

With a whopping 50,000-hour battery life, it’s always game on. User-friendly and lightweight at 5.2 ounces, it features limitless eye relief and supports both-eyes-open shooting. 

It’s not just the long-lasting battery but also the O-ring seal that packs in durability. Truly, it has all the trimmings without the steep price.

Why To Buy 

Look, if you’re after value, this is it. The Vortex Optics Crossfire Gen II offers everything you’d want and then some. Insane battery life? Check. Light on your firearm? Absolutely. 

It’s got a solid build, and, trust me, it holds zero like a champ. And get this: it has both-eyes-open shooting for a better field of view.

Why Not To Buy

Now, don’t get me wrong; it’s a great sight. But there’s a small snag. The brightness knob is a bit on the tricky side to operate. 

Especially if you’re in the middle of an intense session, fumbling around with a knob isn’t ideal. While it’s packed with features, if you’re the kind of person looking for more advanced options like night vision compatibility, then maybe this isn’t your cup of tea. 

Who Should Buy 

So, who’s the target audience for this marvel? Pretty much anyone who wants a dependable and high-performing sight.

Whether you’re a beginner or an experienced shooter looking for a backup sight, it fits the bill. The exceptional battery life alone makes it a compelling buy for long stints at the range or out in the field. 

If durability, ease of use, and a friendly price tag sound like music to your ears, then you’ve found your match.

My Testing 

I took the Vortex Crossfire Gen II for a field test on my Kel Tec Sub 2000. Installation? Smooth as silk. The 2 MOA red dot was sharp, aiding in accurate long-range shots. 

Battery life, of course, was off the charts. The sight felt stable, and it held zero brilliantly. But yeah, tweaking the brightness mid-shoot was a tad bit annoying. Overall, it’s a fantastic sight for the price.


  • Exceptional battery life
  • Holds zero well
  • Both-eyes-open shooting
  • Lightweight
  • Durable O-ring seal


  • Brightness knob can be tricky to operate
  • Limited advanced features

5. SIG Romeo 5 – Solid Option

Meet the Sig Sauer Romeo5, the budget-friendly alternative to the Holosun HS510C. It comes packed with a bright red dot and offers adjustable brightness settings, suitable for daylight or night vision. 

The sight also boasts a Motion Activated Illumination (MOTAC) system, which senses motion to save battery life, totaling an impressive 40,000 hours. It offers two mounting styles—high riser and low profile, both simple to install. 

With limitless eye relief, target acquisition is a cinch no matter where your eyes are positioned.

Why To Buy 

So, why go for the Sig Sauer Romeo5? First off, it’s a bang for your buck kind of deal. It has many of the features that the higher-priced Holosun HS510C offers but at a more manageable cost. 

The MOTAC feature is pretty slick, helping to extend the already generous battery life. Versatility is another key factor; the two mounting options give you the freedom to tailor the sight to your personal preference. 

It’s also IPX-7 waterproof, so a little rain won’t ruin your day. Lastly, the red dot is super crisp, making targeting an absolute joy.

Why Not To Buy 

Alright, let’s talk about the downsides. While it does offer many features, it’s a bit bulkier compared to some other options out there. 

If you’re really into lightweight gear, this could be a sticking point. Also, it lacks some of the more advanced features found in high-end sights. 

Who Should Buy 

Wondering if the Romeo5 is the sight for you? If you’re on a budget but still want a quality sight that’s feature-rich, this is your go-to option. 

Whether you’re a newbie just starting out or a seasoned pro looking for a reliable backup, it fits the bill. It’s particularly good for casual shooters and even for more tactical applications. 

My Testing 

I had the Romeo5 mounted on my Kel Tec Sub 2000 for some field testing. Installation was straightforward, and the red dot was bang-on right from the get-go. 

At distances between 50 and 100 yards, the sight held zero beautifully. The MOTAC system worked like a charm, waking up when I needed it. 

It felt a bit heavier, but nothing too noticeable. Overall, it’s a budget-friendly sight that didn’t disappoint.


  • Long battery life
  • MOTAC feature
  • Versatile mounting options
  • IPX-7 waterproof
  • Limitless eye relief


  • A bit bulkier
  • Lacks some advanced features

6. Burris Fastfire III – User Friendly

Brightness can be adjusted to fit your surroundings. Mounting is a snap, and it even has tool-free elevation and windage adjustments. Plus, its durability is backed by shockproof glass.

Why To Buy 

So you’re eyeing the Fastfire 3, eh? And why not? It’s compact, making it a great fit for concealed carry. Its lightweight design won’t weigh you down, especially during hunting trips. 

One of its standout features is the 3 MOA dot, designed for the kind of pinpoint accuracy that’s great for hitting distant targets.

Why Not To Buy 

Alright, let’s dive into the not-so-great aspects. The Fastfire 3 does have a relatively shorter battery life—just 5,000 hours. In comparison to other models, that’s on the low side. 

Who Should Buy

Is the Fastfire 3 for you? If you own a Kel Tec Sub 2000 and you’re looking for a compact, lightweight sight that delivers in the accuracy department, this is your match. 

It’s particularly good for those who enjoy hunting trips and want to carry their weapon easily.
