The Trijicon RMR Type 2 Adjustable LED Sight is a powerhouse of durability and precision, ideal for your Ruger Mark IV.

Unique Design: Let’s talk about this sight’s unique design. Crafted for impact absorption and stress deflection, the Trijicon RMR Type 2 isn’t just built to last; it’s engineered to thrive. 

The military-grade aluminum housing, specifically 7075-T6 aluminum, protects the lens like a fortress. But it’s not just about durability; this design also helps maintain your aim, particularly when you’re under pressure or in rapid-fire situations. 

The design ensures that the lens remains unaffected, allowing you to shoot with unmatched accuracy.

Durable Material: Material matters. The sight’s 7075-T6 aluminum makes it robust yet lightweight, ensuring it won’t unbalance your Ruger Mark IV. 

Unlike other materials that compromise between weight and toughness, this aluminum type offers the best of both worlds. The material is corrosion-resistant, which means it can handle exposure to the elements without a hitch. Whether it’s rain, snow, or sleet, this sight’s got your back.

Reticle Variety and Size: When it comes to reticles, size does matter, and the RMR Type 2 gives you options. My personal favorite is the 3.25 MOA reticle.

This size optimizes your field of view, making it perfect for both close and medium-range targets. It’s quick to capture and exceptionally precise, making it versatile for various shooting scenarios.

Enhanced Electronics for Reliable Use: The electronics in this sight are like a dependable friend. They offer you exactly what you need when you need it. 

One striking feature is its battery conservation mode, which automatically adjusts aiming brightness according to the environment. This ensures that your sight remains active for extended periods without needing a battery swap. The ruggedized battery housing ensures that your electronics stay protected, enhancing the sight’s overall reliability.

Power-Saving Capabilities: The sight’s power-saving capabilities are nothing short of genius. The automatic brightness adjustment feature not only helps with battery conservation but also ensures optimum visibility in varying light conditions. 

This becomes extremely handy for those who engage in long shooting sessions and don’t want to worry about their sight powering down halfway through.

Button Lockout: The button lockout feature is something every shooter will appreciate. This sets the RMR into automatic mode to prevent accidental adjustments, which could potentially compromise your shot. Imagine having your settings just perfect and then, whoops, you accidentally change something. 

With the button lockout feature, that’s not an issue. This brings an extra layer of reliability to your shooting experience.

Why I Love It: What’s not to love? The Trijicon RMR red dot offers a winning combination of durability, precision, and reliability. 

It elevates my shooting experience to another level, making every session enjoyable and effective. Whether I’m at the range or out in the field, this sight is a trusty companion that has never let me down.

My Experience

The balance was perfect, and my shots became notably quicker and more precise. It was an unmatched seamless experience.

The Trijicon SRO is a sharpshooter’s dream, combining an expansive field of view with unparalleled eye relief and a range of red dot sizes.

Large, Unobstructive Field of View: It’s one of those features you don’t think much about until you experience the difference it can make. 

The Trijicon SRO offers an expansive field that allows for clear visuals not only of your target but also of your surroundings. 

This is especially crucial when you need to make fast decisions based on rapidly changing situations. The glass clarity is top-notch, and it’s not just about seeing your target; it’s about seeing it in a context, and understanding your target’s relation to the environment. 

Eye Relief and Parallax-Free: Tired eyes are the last thing you want during a long day at the range or in the field. Thankfully, this sight offers limitless eye relief, meaning your eyes stay relaxed, allowing you to focus on the task at hand. 

Not to forget, it’s parallax-free. Translation: move your head around all you want, the reticle stays on target. 

Clear, Crisp Red Dot: The red dot on the SRO isn’t a one-size-fits-all deal; you’ve got options. From the precision-focused 1 MOA dot to the quick-targeting 5 MOA dot, you can select the one that suits your specific needs. 

Personally, I find the 2.5 MOA to be the perfect balance for various shooting applications, be it hunting or target practice. 

Top-Loading Battery: Let’s talk convenience. Nobody likes to dismount their optic just to swap out a battery. The SRO sidesteps this issue with its top-loading battery compartment. 

It’s not just about saving time; it’s about maintaining your settings and avoiding the need to re-zero your sight. The battery is a CR-2032 lithium, known for its longevity, so you’re not going to be swapping it out too often anyway.

Easy-to-Adjust Illumination Controls: You’re going to be shooting in all kinds of lighting conditions, right? The SRO has you covered with its easily adjustable illumination settings. 

It offers eight levels of brightness, accommodating anything from the brightest daylight to low-light conditions. So, whether you’re squinting against the sun or straining to see in the dusk, just a few button clicks will give you the visibility you need.

Why I Love It: The Trijicon SRO is an all-in-one package. From its broad field of view to its flexible red dot options and user-friendly features like a top-loading battery and adjustable brightness, it’s an all-rounder. It gives me the confidence to take that shot, knowing full well that I’ve got the support of an excellent optic.

My Experience

Mounting the SRO on my Ruger Mark IV took my shooting experience from great to exceptional. 

The broad field of view gave me context, the eye relief kept me comfortable, and the crisp red dot ensured my shots were accurate.


  • Expansive field of view
  • Limitless eye relief and parallax-free
  • Multiple red dot size options
  • Convenient top-loading battery
  • Easy-to-adjust illumination settings

The Holosun HS507C X2 packs a punch with its Red Super LED, Solar Failsafe, and Shake Awake technology, all housed in durable 7075 Aluminum.

Red Super LED with 50k Hour Battery Life: First things first, the Red Super LED of the Holosun HS507C X2 really stands out. 

We’re talking about a 50,000-hour battery life here. Yep, you read that right. You basically set it and forget it. What I particularly love is the crispness and clarity of the red dot, thanks to the LED technology. 

The 2 MOA dot is precise enough for long-range shooting but also quick for those up-close engagements. 

Shake Awake Technology: So here’s a feature you’re going to love: Shake Awake Technology. How many times have you worried about draining the battery because you forgot to switch off the optic? Well, worry no more. 

The HS507C X2 enters a sleep mode after a set period of inactivity; choose from 10 minutes to 12 hours. The moment you touch it or move your gun, it wakes up instantly. I mean, how cool is that? It’s not just a battery saver; it’s peace of mind.

Housing Material and Durability: Holosun didn’t cut any corners with the housing material. We’re looking at 7075 T6 Aluminum here. 

For the uninitiated, that’s the same grade of aluminum used in aerospace engineering. It’s rugged and built to last. 

Even after a few accidental bumps and drops, the sight holds its zero, and the housing doesn’t show any signs of wear and tear. I’ve put it through its paces, and it’s stood up to every test.

Window Size and Reticle Options: The window size on this sight is 0.63×0.91 inches, giving you plenty of room to quickly acquire and maintain your target. The reticle offers versatility with a 2 MOA red dot and a 32 MOA circle. 

This combination enables quick target acquisition for close quarters while still offering the precision needed for longer shots. Having options is always a good thing, and Holosun delivers on this front.

Why I Love It: What’s not to love about the HS507C X2? It’s like the Swiss Army knife of red dot sights. The 50,000-hour battery life, the smart Shake Awake tech, and the Solar Failsafe feature combine to make this sight a reliable companion for any shooting application.

The Vortex Venom optic is a compact and efficient red dot sight, offering quick target acquisition and clarity, making it a top choice for the Ruger Mark IV 22/45 Lite.

Rapid Target Acquisition: Let’s dive into the nitty-gritty of this sight’s bread and butter: rapid target acquisition. With a 3 MOA reticle, you can get your aim on target in no time flat. 

There’s a certain comfort in knowing that your equipment is working as hard as you are to get that aim right. The 3 MOA size strikes a balance between speed and accuracy, so you’re not trading off one for the other.

Wide Field of View: Ever felt like you’re looking through a peephole when you’re trying to aim? Say goodbye to that feeling with the Vortex Venom. 

The wide field of view in this sight is like watching an IMAX movie but for shooting. You get an expansive visual area that helps you keep track of everything that’s going on; no more losing sight of your target because your view was too narrow. 

Clean Reticle: The reticle appears clean and unblemished in various lighting conditions. What does this mean for you? Well, for starters, it means that your shots are more likely to hit their mark because you’re seeing things clearly. 

The reticle also adapts well to different backgrounds, so it remains clearly visible whether you’re aiming against a dark forest or a bright sky.

Affordability: Alright, affordability time! The Vortex Venom offers premium features without breaking the bank. 

The sight provides a range of features; like the wide field of view and rapid target acquisition; that are often only found in much pricier models.

It proves that you don’t need to shell out big bucks to get top-notch features. This sight has genuinely made shooting with my Ruger Mark IV a more enjoyable and efficient experience.

The Burris FastFire 3 is a lightweight, affordable reflex sight that offers speed and precision, making it a fantastic match for the Ruger Mark IV 22/45 Lite.

Top Battery Access: Let’s start with a feature we all care about battery life and access. The Burris FastFire 3 has top battery access. 

What does that mean for you? Well, it’s all about convenience. You can swap out the battery without removing the sight. 

MOA Dot Sizes: The Burris FastFire 3 offers two MOA dot sizes: 6 or 8. The 8 MOA dot size stands out, especially in bright daylight conditions. 

It’s as clear as day and is pretty hard to miss. It outshines the 6 MOA dot in terms of visibility and crispness. However, the 6 MOA is no slouch either; it holds its own. 

The choice between the two comes down to your personal preference and the shooting conditions you find yourself in most frequently. Whether you like a smaller or larger dot size, you’ve got options, and that’s always a good thing.

Auto Brightness Control: Talk about being smart! The Burris FastFire 3 has an auto-brightness control feature. It adjusts the brightness of your reticle according to the environmental lighting conditions. No more squinting or straining your eyes to see the reticle. 

Durability & Affordability: Affordability and durability often don’t go hand in hand, but the FastFire 3 is a happy exception. You’re getting a sight that’s both affordable and built to last. 

With a battery life that lasts up to 4+ years, this sight is in it for the long haul. It holds up well against regular wear and tear, a factor often overlooked when shopping for sights. 

Why I Love It: The Burris FastFire 3 checks all the boxes for me. It’s affordable without skimping on features or durability. I’m a big fan of the top-loading battery access and the automatic brightness control. 

Those features just make life easier, you know? And let’s not forget the option between 6 or 8 MOA dot sizes. It’s like this sight is telling you, “Hey, you do you!”

My Experience

Radiant Ambient Light Sensor: Now, let’s talk about how smart this sight is. The Radiant Ambient Light Sensor adjusts the reticle brightness automatically based on the surrounding light. 

This feature ensures that the Ruger Mark IV remains an all-weather, all-lighting-condition friend. 

Automatic Activation: Wait, there’s more! The RAD Pro has a motion sensor that kicks into action when it senses weapon movement. 

Basically, it knows when it’s game time and lights up accordingly. But that’s not all; it also knows when to take a nap. If it doesn’t sense movement for two minutes, it enters sleep mode. 

Manual Power and Auto Shutoff Functions: Even though this sight is pretty clever, you’re still the boss. It provides manual power and auto-shutoff options, allowing you to take control when you want to.
