The Trijicon RMR Type 2 is a robust, versatile red dot sight built for extreme reliability in various environments.

3.25 MOA Adjustable LED RMR: This feature is a game-changer. The 3.25 MOA dot is just the right size for both precision at distance and quick target acquisition close up. The adjustable LED brightness is a big plus. 

You get eight settings to play with, including two for night vision and one super bright setting for sunny days. What’s cool is how it transitions smoothly between these settings, adapting to different lighting conditions almost seamlessly. 

Whether you’re in a dimly lit indoor range or out in broad daylight, this sight has got you covered.

Dependable Electronic Design: This sight is like a tiny tank. The ruggedized battery contacts and electronics are designed to survive tough conditions. When you’re out in the field, the last thing you want to worry about is your sight failing. 

This design ensures that it stays operational, even in harsh environments. Think about it; whether you’re in a dusty desert or a humid forest, this sight keeps performing. It’s particularly impressive when mounted on high-recoil firearms, where other sights might struggle to maintain their performance.

Unique Patented Housing Shape: The housing shape of the RMR Type 2 is quite innovative. Forged from military-grade aluminum alloy, it’s built to take a beating. 

This isn’t just about looks; the housing diverts impact away from the lens, which significantly ups its durability. I remember dropping it once (accidentally, of course), and it just shrugged off the impact. 

For anyone who’s out in the field a lot, or if you’re a bit clumsy like me, this feature is a lifesaver. It means your sight is more likely to survive the bumps and knocks of regular use.

Battery Conservation Mode: Let’s talk about battery life. The RMR Type 2’s battery conservation mode is fantastic. After 16.5 hours, it auto-adjusts the dot brightness based on ambient light conditions. This is great for two reasons. 

Firstly, you don’t have to fret about the battery dying on you when you need it most. And secondly, this feature means the sight is always at the optimal brightness for your current environment. With over four years of continuous use at a mid-setting at room temperature, you won’t be constantly worrying about changing batteries.

Button Lockout: The button lockout feature is a thoughtful addition. It allows the sight to operate in automatic mode, preventing accidental adjustments. 

This is crucial, especially in high-pressure situations where you can’t afford any mistakes. By locking the settings, you ensure that the sight performs exactly how you need it to every time. It’s kind of like setting it and forgetting it; you can focus on your target, not on fiddling with your sight.

Why I Love It: Honestly, what’s not to love? The Trijicon RMR Type 2 hits the sweet spot between ruggedness, reliability, and versatility. Its perfect dot size, adaptive brightness, and rock-solid design make it an all-rounder. 

Whether I’m at the range, out on a hunt, or just practicing, this sight has never let me down. It feels like an extension of the firearm, seamlessly integrating into whatever scenario I’m in.

My Experience 

Using the RMR Type 2 has been a seamless experience. Adjusting to different lighting conditions is effortless, thanks to the automatic brightness settings.

Whether you’re shooting in bright daylight or lower light conditions, the dot remains distinct and easy to focus on, contributing significantly to shooting accuracy.

Windage & Elevation: What I love about the SRO is the tool-less design for windage and elevation adjustments. It’s incredibly user-friendly and makes zeroing in hassle-free. 

You don’t need to fiddle with small tools or worry about losing them in the field. The adjustment knobs are tactile and provide precise feedback, allowing for accurate and easy modifications on the fly.

This feature is particularly handy during dynamic shooting sessions or when switching between different shooting ranges, as it saves time and keeps you focused on your target.

Same Footprint as RMR: Sharing the same footprint as the Trijicon RMR is another feature that sets the SRO apart. It offers more flexibility in terms of use across different firearms and setups, making it a versatile choice for many shooters. 

Top Loading Battery: The top-loading battery feature of the SRO is a thoughtful design aspect. This means you can easily change the battery without having to remove the sight from the firearm, maintaining your zero. 

This is incredibly convenient and saves time, especially when you need a quick battery change in the middle of a shooting session or competition. The CR2032 battery provides over 3 years of continuous use at setting 4 of 8, which is impressive and means less worry about battery life during critical moments.
