Top 5 Best Red Dot For Shadow Systems MR920 in 2024

Holosun 507K

⁠

I've been on the hunt for the perfect red dot to pair with my Shadow Systems MR920, and after trying out several options, I'm convinced the Holosun 507K is exactly what I was looking for. Let me tell you why:

Specifications:

Reticle: Choose between a 2 MOA red dot, a 32 MOA circle, or a circle-dot combination via Holosun's Multiple Reticle System (MRS).

Housing: Rugged 7075 aluminum

Adjustments: Easy-to-use side-mounted buttons

Battery Life: An incredible 50,000 hours on a single CR1632 battery, aided by Holosun's Solar Failsafe and Shake Awake technologies.

Mounting: Requires an adapter plate for a perfect fit on the MR920.

Best Features:

Versatility: With the MRS system, I can switch between reticle styles to suit my shooting situation.

Durability: That aluminum housing feels like it could handle pretty much anything I throw at it.

Battery Life: Forget about constantly swapping batteries, Holosun absolutely excels in this area.

Shake Awake: It's ready when I pick up the pistol, saving me precious moments.

Advantages:

Cost-Effective: It's loaded with features but still remains a very fairly priced optic.

Compact: Adds minimal bulk or weight to the MR920.

Clarity: Excellent sight picture with minimal distortion.

Intuitive Controls: I find Holosun's side buttons super easy to use and adjust, even with gloves on.

Disadvantages:

Adapter Plate: Unlike some red dots specifically designed for Shadow Systems, an adapter plate is needed.

Reticle Brightness in Extreme Sunlight: Some users mention the reticle can be harder to see in very bright conditions.

My Experience

The Holosun 507K has made my MR920 even more enjoyable to shoot. It's crazy fast for close-quarters target acquisition with the circle, but I still get the accuracy boost of that 2 MOA dot for longer shots. Once I got everything zeroed, it's consistently held true through multiple range sessions.

What Others Are Saying

I always like to supplement my own opinions with some wider research. Here's what others are saying about the 507K:

"Best bang for your buck red dot on the market."

"The Shake Awake is an absolute game-changer."

"I wish it didn't need an adapter plate for my pistol, but it's still worth it."

Overall, I can't praise the Holosun 507K enough. If you own a Shadow Systems MR920, you owe it to yourself to give this optic a serious look.

Holosun 407K

⁠

The Holosun 407K red dot sight is a solid contender for my Shadow Systems MR920. It's a compact option that packs a punch, but there are a few things to consider before you buy. Here's my breakdown:

Specs and Features:

Compact Size: Similar to the 507K, it maintains a low profile, ideal for concealed carry with the MR920.

6 MOA Dot: The dot is a bit bigger than the 507K's 2 MOA, offering faster target acquisition but potentially sacrificing some precision at distance.

Shake Awake: Just like the 507K, this feature wakes the sight with movement, keeping it ready when you need it.

Side Battery Tray: No need to remove the sight entirely for battery changes, a big plus.

Best Features:

Concealment Ready: The size keeps the MR920 comfortable to carry without sacrificing much sight picture.

Fast Acquisition: The 6 MOA dot makes finding your target super quick, especially in close quarters.

Easy Battery Access: The side battery tray is a lifesaver. Battery changes are simple and don't require re-sighting the optic.

Disadvantages to Consider:

Dot Size: While great for quick acquisition, the 6 MOA dot might not be ideal for long-range shooting where precision is key.

Limited Window: Compared to some red dots, the viewing window feels a little small. It might take some getting used to for shooters with larger red dots.

My Experience:

The Holosun 407K has definitely improved my shooting with the MR920. The red dot is easy to pick up, and the shake awake feature is fantastic. However, I do find myself wishing for a slightly smaller dot size for those times I want to stretch out at the range. The window size also took a little while to adjust to coming from a larger red dot.

What People Are Saying Online:

Here's what MR920 owners are saying about the 407K:

Many love the compact size and ease of concealed carry.

The 6 MOA dot gets praise for speed, but some wish for a 2 MOA option.

The side battery tray and long battery life are frequently mentioned as pros.

Final Verdict:

The Holosun 407K is a great red dot sight for the Shadow Systems MR920, especially for concealed carry. The fast target acquisition and easy battery access are fantastic. However, if you prioritize long-range precision or a larger sight picture, you might want to consider the 507K with its 2 MOA dot.

Sig Sauer RomeoZero

⁠

I wanted to find a streamlined, budget-friendly red dot for my Shadow Systems MR920, and the Sig Sauer RomeoZero seemed like a solid contender. While it delivers in some areas, there are a few things to carefully consider before making the jump.

Specifications:

Reticle: 3 MOA or 6 MOA red dot options.

Lens: Polymer with coatings for scratch-resistance and light transmission.

Housing: Polymer

Weight: Lightweight at just over an ounce.

Battery: CR1632 with MOTAC (Motion Activated Illumination System) to conserve battery.

Best Features:

Price: One of the most affordable red dots from a major brand.

Ultra-Compact Size: A seamless fit that doesn't add bulk to the MR920's profile.

MOTAC: Love the idea of automatic illumination for rapid target acquisition.

Advantages:

Easy to Install: Mounts directly to the MR920, no adapter plates necessary.

Good Sight Picture: The polymer lens is clear enough for most shooting situations.

Ease of Use: Simple adjustments and the MOTAC feature are convenient.

Disadvantages

Durability: The polymer construction doesn't inspire the same confidence as more rugged metal-bodied optics.

Battery Life: Reports of shorter-than-expected battery life are common.

Lens Distortion: There's some noticeable distortion around the edges of the lens.

My Experience

My experience with the RomeoZero has been mixed. On one hand, it functions as intended. It's great for getting on target quickly within typical pistol ranges, and it holds zero well enough for casual shooting. However, I do worry about its ability to take a beating over the long term, and the battery life has been underwhelming.

What Others Are Saying

Here's a sampling of what other MR920 owners are saying about the RomeoZero:

"A decent starter red dot, but I eventually upgraded to something more durable."

"Great value for the money if you're just getting into red dots."

"Battery dies too quickly for my liking."

Overall, the Sig Sauer RomeoZero can be a good choice for the Shadow Systems MR920, but it depends on your priorities and how hard you plan to use it. If you want a super budget-friendly optic for basic range fun, it might be perfect.

If you need something built to withstand rougher treatment, look into slightly more expensive but more durable options.

Holosun EPS Carry

⁠

The Holosun EPS Carry red dot sight has become my go-to for my Shadow Systems MR920. It's a culmination of what I've been looking for in a red dot: ultra-concealable, feature-packed, and built for everyday carry. Here's why I love it:

Specs and Features:

Super Slim Profile: This is the real star of the show. The EPS Carry sits incredibly low on the MR920's slide, making it practically disappear for discreet carry.

Dual Reticle System (DRS): Choose between a 2 MOA dot for precision or a 6 MOA circle for quick acquisition. I can switch on the fly depending on the situation.

Solar Power: A bonus feature! The solar panel helps extend battery life, and even acts as a backup power source in case the battery dies.

Shake Awake: Like other Holosun red dots, the EPS Carry wakes with the slightest movement for instant readiness.

Best Features for Me:

Concealment King: This red dot practically disappears on the MR920. No more printing or snagging on clothing – perfect for everyday carry.

Reticle Versatility: Having the option between a precise dot and a fast-acquisition circle makes the EPS Carry adaptable to any situation.

Always Ready: The shake awake and solar features give me peace of mind knowing the sight will be on when I need it.

Are There Any Drawbacks?

Not many, but a few things to consider:

Limited Availability: The EPS Carry is a relatively new red dot, so finding one in stock can be tricky.

Cost: It's on the pricier side compared to some other Holosun red dots.

Iron Sight Use: Due to the low profile, using backup iron sights isn't really an option.

My Experience:

The EPS Carry has transformed the way I carry my MR920. It's comfortable, disappears under clothing, and the red dot makes target acquisition incredibly fast. The reticle options are a huge plus, allowing me to adjust on the fly. While I do miss having backup iron sights as an option, the overall benefits outweigh that drawback for me.

What People Are Saying Online:

MR920 owners who've gotten their hands on the EPS Carry are raving about it:

Concealment is the most mentioned benefit, with people loving how slim it is.

The DRS gets high marks for its versatility.

Solar power and long battery life are frequently mentioned as pros.

Final Verdict:

If you're looking for the ultimate red dot for concealed carry with your Shadow Systems MR920, the Holosun EPS Carry is hard to beat. It's slim, feature-rich, and built to last. Just be prepared to hunt for one and pay a bit of a premium for its cutting-edge design.

Trijicon RMRcc

⁠

The Trijicon RMRcc red dot sight is undeniably a top-of-the-line optic. It's known for its ruggedness and reliability, making it a tempting choice for my Shadow Systems MR920. However, after trying it out, I have some thoughts on whether it's the perfect fit.

Specs and Features:

Proven Durability: Trijicon sights are legendary for their bomb-proof construction. This RMRcc is no exception.

Tritium Illumination: No batteries needed! The tritium vial provides a constant red dot, even in low-light conditions.

Multiple Reticle Options: Choose between a 3.25 MOA dot or a 6.5 MOA circle dot for a balance of precision and speed.

Small Footprint: Compared to some RMRs, the RMRcc is a more compact option. However, it's still larger than some micro red dots.

Best Features:

Legendary Toughness: I can trust this sight to take whatever punishment I throw at it, giving me confidence in any situation.

Night Vision Compatibility: The tritium illumination works with night vision gear, making it a versatile option.

Always On, Always Ready: No need to worry about dead batteries with the tritium illumination.

Potential Drawbacks to Consider:

Size and Weight: While smaller than some RMRs, the RMRcc still adds some bulk and weight to the MR920, which might not be ideal for concealed carry.

Cost: Trijicon sights come with a premium price tag.

Limited Window: The sight picture feels a bit smaller compared to some other red dots.

My Experience:

The Trijicon RMRcc is undeniably a fantastic red dot. It's built like a tank and the tritium illumination is a game-changer. However, the size and weight were noticeable on my MR920, especially for concealed carry. The smaller sight window also took some getting used to.

What People Are Saying Online:

MR920 owners who use the RMRcc have mixed reviews:

Praises for the bomb-proof construction and tritium illumination.

Some love it for open carry or range use, but find it bulky for concealed carry.

The smaller sight window is a point of discussion, with some adjusting quickly and others preferring a larger window.

Final Verdict:

The Trijicon RMRcc is an exceptional red dot sight, but for my Shadow Systems MR920 specifically, it's a bit of a compromise. If you prioritize absolute ruggedness, night vision compatibility, and always-on illumination, it's worth the size and weight tradeoff. However, if a slimmer profile for concealed carry or a larger sight window is more important, you might be happier with a different option.
