Features Comparison: Trijicon RMRcc Vs Holosun 507K

1. Optical Clarity and Vision Comfort

Trijicon RMRcc

The Trijicon RMRcc stands out with its sharp and clear 3.25 MOA dot. It’s particularly friendly to my slightly astigmatic eye, offering a more defined dot compared to the 507K. 

This clarity becomes more evident in low-light conditions. However, the RMRcc’s brighter setting does lead to more bloom, which can be a bit distracting. The tint on the RMRcc, though a bit darker, doesn’t hinder the sight picture much. 

The softer edges of the RMRcc’s body are a subtle yet appreciated design aspect, especially during close body carry.

Holosun 507K

The 507K’s 2 MOA dot, though slightly less sharp to my eye, is still very clear. The lower tint level is less straining on the eyes, making prolonged use more comfortable. 

The fisheye effect is noticeable but doesn’t detract significantly from the overall experience. In terms of comfort and visual ease, the 507K is more forgiving, especially in extended shooting sessions.


Trijicon RMRcc, with Its superior dot sharpness and clarity, gets the edge, despite the 507K’s more comfortable tint and less noticeable fisheye effect.

2. Durability and Design

Trijicon RMRcc

The RMRcc’s robust design is impressive. Its patented housing shape effectively diverts impact, enhancing durability. The design feels solid and reliable, which I appreciated during field tests. The tougher exterior, however, makes the buttons harder to press. 

This might be a small gripe, but in high-stress situations, ease of use is crucial. The softer edges are a nice touch, especially when holstering and unholstering.

Holosun 507K

The 507K’s aluminum housing is sturdy but doesn’t feel as rugged as the RMRcc. It’s more streamlined, which is great for quickdraws. 

The buttons are more tactile and easier to operate than the RMRcc’s. While it may not match the RMRcc in terms of impact resistance, it certainly holds its own in everyday use scenarios.


Trijicon RMRcc is designed for durability, and its impact resistance is unparalleled, making it a solid choice for those who prioritize ruggedness.

3. Battery Life and Maintenance

Trijicon RMRcc

The RMRcc boasts a battery life of up to 4 years, which is quite impressive. However, the bottom-loading battery design is a bit of a letdown. 

During my testing, this meant having to remove the sight for battery changes, which isn’t ideal. Despite this, the long battery life means this won’t be a frequent Issue.

Holosun 507K 

The 507K offers an exceptional battery life of up to 50,000 hours, and the side-loading battery tray is a game-changer. 

It allows for easy battery replacement without the need to remove the sight from the firearm. This is a huge plus in terms of convenience and maintaining zero.


Longer battery life and user-friendly battery replacement system of the Holosun 507K give it a significant advantage over the RMRcc.

4. Optical Clarity and Field of View

Trijicon RMRcc

The RMRcc’s optical clarity is remarkable. The 3.25 MOA dot is sharp and well-defined, which I found to be a significant advantage during precision shooting. 

The field of view is somewhat restricted due to its smaller size, but this is a trade-off for its compact design. The slight blue tint on the lens didn’t affect visibility much, but it was noticeable in certain lighting conditions.

Holosun 507K

The 507K offers a clean and clear view with minimal distortion. The field of view is slightly wider than the RMRcc, which I appreciated during rapid target acquisition drills. 

The lack of a blue tint made for a more natural viewing experience. However, the ‘fisheye’ effect was more pronounced in the 507K, which might be distracting for some shooters.


Despite a slightly smaller field of view, the RMRcc, with its superior optical clarity and less pronounced fisheye effect, gets the edge.

5. Ease of Use and Interface

Trijicon RMRcc

The RMRcc’s interface is straightforward, with easy-to-understand controls. The buttons, though a bit stiff, offer a reassuring sense of quality and durability. 

Adjusting settings is intuitive, but I found the button resistance to be a minor hindrance during rapid adjustments.

Holosun 507K

The 507K shines in its ease of use. The buttons are more tactile and easier to press compared to the RMRcc. Adjusting settings on the fly was easy. 

The interface is user-friendly, making it a great choice for shooters who prioritize quick adjustments over ruggedness.


Holosun 507K takes the lead with its more tactile buttons and user-friendly interface that make it more convenient for rapid use.

6. Reticle Options and Versatility

Trijicon RMRcc

The RMRcc offers a single, crisp 3.25 MOA dot. While this is great for precision, it lacks versatility in terms of reticle options. For shooters who prefer simplicity and a classic dot reticle, the RMRcc is a perfect fit.

Holosun 507K

The 507K offers more reticle versatility with its Multi-Reticle System. Having the option to switch between a 2 MOA dot and a 32 MOA circle dot provides flexibility for different shooting scenarios. 

This feature is particularly useful for shooters who engage in various types of shooting disciplines.


Holosun 507K is a winner in this category with its multiple reticle options that provide greater versatility for different shooting needs.
