The Trijicon RMR Type 2 is a premium, military-grade red dot sight with versatile features designed for optimal performance and durability.

3.25 MOA Adjustable LED RMR: This sight features a 3.25 MOA red dot reticle that’s exceptionally bright and crisp. The LED RMR is adjustable with up to eight brightness settings, including two for night vision and one super-bright setting. 

This flexibility allows you to have the ideal brightness in various lighting conditions, be it high noon or twilight. With this sight, you’re not just buying an optic; you’re investing in a flexible, user-friendly tool that enhances your shooting precision drastically.

Dependable Electronic Design: What sets this sight apart is its ruggedized electronic design, including battery contacts that are built to last. You can trust this sight to perform even in extreme conditions like heavy rain or muddy terrains.

It’s essentially a reliable companion that stays consistent in performance, giving you one less thing to worry about when you’re out and about.

Unique Patented Housing Shape: Constructed from military-grade aluminum, the patented housing shape of the sight not only withstands impact but also intelligently diverts any force away from the lens. 

So, even if you accidentally drop your Glock 23, the sight remains protected, ensuring longevity and consistent performance.

Battery Conservation Mode: This feature is something of a game-changer. After 16.5 hours, the sight automatically adjusts the brightness of the aiming dot according to the ambient lighting. This battery conservation mode offers a whopping four years of continuous use, eliminating the annoyance of frequent battery replacements.

Button Lockout: It’s a nifty feature that sets your RMR into an automatic mode, locking out manual adjustments. This ensures that your settings remain intact and accidental button pushes don’t mess up your aim.

Why I Love It: Simply put, this sight is an all-rounder. From its rugged construction to its exceptional brightness options, it checks all the boxes.

The Trijicon SRO is a high-performance red dot sight with features like top-notch durability, water and shock resistance, and an expansive field of view.

Rugged, Durable Construction: The first thing you’ll notice about the Trijicon SRO is its robustness. Made from 7075 T6 Aluminum, the sight is virtually indestructible. 

This particular alloy ensures not only high durability but also a smooth texture that resists wear and tear over time. Additionally, the lens frames are crafted from premium materials that are scratch-resistant. 

Durability is one area where this sight really shines, so whether you’re a hobbyist or a professional, you’ll appreciate this feature.

Resistance to Water and Shock: Resistance to water and shock are vital factors in any optic, and the Trijicon SRO excels in both. The unit is water-resistant and capable of functioning in moisture-laden environments and even underwater up to ten feet. 

Large, Unobstructive Field of View: For me, a wide field of view is an absolute necessity, and the Trijicon SRO delivers. The sight has exceptional glass clarity, providing an expansive and unobstructed view of your surroundings. 

This feature allows for better situational awareness, which can be critical when you need to be accurate and quick on the draw.

Eye Relief and Parallax-Free: The SRO also impresses when it comes to eye comfort. With unlimited eye relief, you won’t experience any strain during long shooting sessions. It also boasts a parallax-free nature, ensuring that your reticle remains in place even when you move your head or attempt adjustments.

Clear, Crisp Red Dot: The reticle is available in three variations: 1 MOA, 2.5 MOA, and 5 MOA dots. Each has its own set of benefits, depending on your shooting requirements. 

The 1 MOA dot is excellent for long-range and bullseye shooting, while the 2.5 MOA dot is versatile enough for competition, hunting, and general target practice. The 5 MOA dot, while not as precise, is bold and ideal for close-up shooting.

Top Loading Battery: I can’t emphasize enough how convenient this feature is. The battery compartment is on the top, which means you don’t have to remove the sight from your firearm for replacements. 

Powered by a CR-2032 lithium battery, this sight ensures you’re always ready for action.

Easy-to-Adjust Illumination Controls: With up to eight brightness settings, adjusting the illumination is a cinch. Whether you’re in broad daylight or in low-light conditions, you can easily toggle between the settings to find the optimal brightness level.

Why I Love It: This sight is a true workhorse, crafted to meet the needs of any shooting enthusiast. From its durable construction to its user-friendly features, it’s a sight that doesn’t disappoint.

Now, what’s special about that? Well, this particular aluminum alloy is super robust and lightweight, giving the sight a rugged framework.

What it does is ensure optimum light wave transmission while keeping the lens resistant to wear and shock. 

Waterproof Abilities: Weather is unpredictable, but your sight shouldn’t be. The Holosun 507C comes with an IPX-6 rating, which, in layman’s terms, means it can handle some pretty serious moisture.

It aligns perfectly with the barrel of your Glock 23, minimizing what’s called parallax error. That’s the visual distortion that can throw off your shot if the sight’s reticle doesn’t align well with the target. 

Multi-Coated Lens and Armortek Coating: The lenses are fully multi-coated, which means no distortion and a crystal-clear view of your target. But let’s go a step further with the Armortek coating.

Durable Construction: The Viper’s durability deserves a special mention. With a hard-anodized finish and a low-glare matte texture, this sight is built like a tank. It’s not just waterproof; it’s also shockproof. 

Whether you’re on a peaceful range or out in the wild, this sight can withstand whatever you throw at it. Feel free to challenge it. Honestly, it loves a good challenge and won’t let you down.

Elevation and Windage Adjustments: Precision is key, and the Vortex Viper allows for precise adjustments to both elevation and windage. 

Yes, the two locking screws might seem like a bit of a hurdle, but trust me, it’s worth the extra minute. Once adjusted, it’s rock solid. No drifts, no unintended movements; just sustained accuracy. So, yes, the initial setup might need some getting used to, but the payoff is tremendous.

Why I Love It: The Vortex Viper packs a punch with its blend of technological sophistication and practical functionality. The low-mounting profile enhances accuracy while the multi-coated lenses ensure a pristine view.
