The Sig Sauer ROMEO 5 is a 1X20mm red dot sight built to elevate your shooting game, particularly with the Kel Tec Sub 2000.

Clarity and Multi-Coated Lens: The Romeo 5 comes with a multi-coated lens that allows for some incredibly crisp and vivid visuals. This is especially helpful in scenarios with less-than-ideal lighting conditions. 

While some other optics struggle with low light, this lens brings the environment right to your eye, effectively maximizing the available light. 

The field of view is practically unlimited, and the sight is parallax-free, so your aiming point and the target are going to remain constant, regardless of eye position.

Illumination Settings: Here’s the kicker: the Romeo 5 offers a staggering 10 illumination settings. These options allow you to adapt the reticle’s brightness according to your environment. 

Say you’re shooting under blazing sunlight; you can crank the brightness up. Conversely, you can lower it down a notch if it’s a cloudy day. 

This flexibility can make a significant difference in your shooting accuracy, especially when time is of the essence.

Durability and Weather Resistance: Constructed from high-quality aluminum alloy, the Romeo 5 can take a beating and keep on ticking. 

It’s not just a fair-weather friend; it’s got IPX-7 waterproof and fog-resistant capabilities. That means, come rain or shine, your sight is good to go. 

Affordability: When it comes to value, the Romeo 5 punches well above its weight. You’re getting features often found in higher-priced models. 

In today’s market, getting this kind of quality at this price range is like finding a needle in a haystack. So, if you’re looking for a high-performance red dot sight without breaking the bank, this is it.

Side Flip Mount Compatibility: The icing on the cake? This sight is compatible with a side flip optic mount for the Sub 2000. 

It simplifies the mounting and demounting process, especially when you need to fold the Sub 2000 for transport. This added convenience might seem small, but it adds to the overall experience in a big way.

Why I Love It: The Sig Romeo 5 isn’t just another red dot sight; it’s a top-notch performer that comes at an unbeatable price. It’s the total package: clear visuals, versatile settings, and rock-solid durability.

My Experience

Oh man, it felt like a match made in heaven. The sight performed flawlessly, making my time at the range an absolute joy. Target acquisition was fast, and the adjustments were intuitive.

The Bushnell Trophy TRS-25 is a budget-friendly red dot sight that offers reliability and performance without breaking the bank.

Designed to handle recoil-heavy firearms like the Kel Tec Sub 2000, this sight’s ruggedness is a testament to its durability. It’s a no-brainer if you’re looking for a sight that can take a beating and keep on ticking.

I’ve been testing this sight for a few weeks now, and I’m pretty much sold. The 3 MOA dot was bright and clear, and it held zero like a champ, even after a few hundred rounds. Adjusting the brightness was a cinch, and the sight stayed snug on the rail through all the recoil.

Trijicon MRO offers an expansive field of view, built-like-a-tank durability, and versatile mounting options for serious shooters.

Expansive Field of View: The Trijicon MRO takes field of view to a new level, primarily due to its tapered tube design. 

It’s a significant advantage when you’re shooting in dynamic conditions where situational awareness is critical. 

The tube effect, a common issue in other sights where it feels like you’re looking through a pipe, is virtually nonexistent here. You see more of the environment, which is crucial when you’re switching between multiple targets or keeping track of a moving object.

Unmatched Durability: Let’s talk about toughness. The MRO isn’t just built to meet mil-spec durability standards; it crushes them. 

Whether you’re dealing with accidental drops, heavy recoil, or even an occasional kick, this sight keeps its composure and, more importantly, maintains its zero.

Why I Love It: It’s a total package for me: the wide field of view, the rugged construction, and the freedom to use different mounts make the MRO an invaluable addition to my shooting gear.

My Experience

I’ve field-tested this sight rigorously, and it has performed exceptionally well. The wide field of view keeps me aware of my surroundings at all times, an essential attribute when tracking multiple targets.

The Vortex Crossfire Red Dot Sight offers excellent performance and reliability, all while being budget-friendly.

Long Battery Life: One of the first things that struck me about this sight was its insane battery life of 50,000 hours. It’s a no-brainer that a prolonged battery life is a boon for any sight, allowing you to focus on the task at hand without worrying about constantly swapping out batteries. 

It uses a CR 2032 battery, which is pretty standard and easy to find. The longer battery life makes it a trusty companion, whether you’re at the range or in the field.

Weatherproof Construction: Another feature that makes the Vortex Crossfire a solid choice is its resilience against harsh weather. It’s both waterproof and fog-proof. 

It’s got O-ring seals, ensuring that no moisture can enter the optic and thereby ensuring it stays fog-free even under rapid temperature changes. 

This weatherproofing gives it the flexibility to be used in pretty much any environmental condition.

Crystal-Clear Optics: The 2 MOA red dot is quick to acquire and offers excellent visibility even in lower light conditions. 

The multi-coated lens ensures that light transmission is at its peak, allowing for a clearer sight picture. What’s more, the red dot intensity can be adjusted to suit different lighting conditions.

Rugged Build: Crafted from aluminum, the Crossfire is not just lightweight but also remarkably durable. 

The housing is rugged enough to protect the lens from any physical harm, accidental falls, and even water damage. I’ve given it a run for its money in different terrains, and it’s stood up to the test.

Why I Love It: The Vortex Crossfire ticks a lot of boxes for me: long battery life, tough as nails, and doesn’t break the bank. It does exactly what it says it will do, and it does it well.

My Experience

I’ve tested the Vortex Crossfire extensively on my Kel Tec Sub 2000, and it’s been a game-changer. The sight was super easy to mount, and it held zero perfectly, even after several hundred rounds. 

The battery life has been excellent, and the weatherproof features have come in handy during some unexpected rain.


  • Long-lasting 50,000-hour battery life
  • Waterproof and fog-proof construction
  • Easy to acquire 2 MOA red dot
  • Affordable pricing
  • Durable aluminum housing


  • Lack of magnification limits its range
  • Brightness settings could be improved for more versatility

The sight is super intuitive; there are no complex menus or sub-menus to navigate. You’ve got a basic, clear 3 MOA red dot that you can sight in quickly. The easy-to-use design helps you to get into shooting sports without feeling overwhelmed by technology.

Automatic Brightness Sensor: One of the standout features here is the automatic brightness sensor. This sensor adjusts the brightness of the red dot according to your environment. 

The sight also provides manual brightness settings, which you can use to fine-tune the brightness according to your preference.

Durability & Weather Resistance: In terms of build quality, this sight doesn’t disappoint. It’s waterproof and fog-proof, just like you’d want in any quality sight. 

The device is sturdy and can withstand the recoil of your Kel Tec Sub 2000 without losing zero. I’ve put this thing through some tough conditions, and it’s held up like a champ.

Top Battery Access: Changing the battery is a breeze with top access to the battery compartment. You don’t have to detach the sight from the firearm, making the whole process quicker and simpler. 

Trust me, this feature is a time-saver, especially if you’re out in the field.

Why I Love It: The Burris FastFire offers a blend of simplicity and functionality that’s hard to beat, especially for those new to shooting sports. 

The automatic brightness sensor is the cherry on top, ensuring the red dot is always at an optimal brightness.

My Experience

I mounted the Burris FastFire on my Kel Tec Sub 2000 and took it for a test drive. The sight performed exceptionally well. From the ease of mounting to holding zero after hundreds of rounds, it was a pleasure to use.

The top battery access made life simpler when it was time for a battery change.
