Understanding the Differences Between Holosun EPS Carry MRS and Holosun 507K
07/10/2024
Considering open and closed emitter for your optic? We've compared two Holosun models; The Holosun EPS Carry MRS and Holosun 507K
TL:DR
The Holosun EPS Carry MRS and Holosun 507K are both excellent red dot sights, but they cater to different needs.
The EPS Carry MRS features an enclosed emitter for enhanced durability and environmental protection, while the 507K offers a lighter, open emitter design for a broader field of view.
Both models include a Multi-Reticle System with 2 MOA dot and 32 MOA circle options.
The EPS Carry MRS uses a modified K footprint, whereas the 507K uses the Shield RMSc footprint.
Battery access also differs, with the EPS Carry MRS offering a side-mounted tray and the 507K having a bottom-mounted compartment. Choose the EPS Carry MRS for rugged protection or the 507K for compact convenience.
The Long way home....
1. Design and Form Factor
- EPS Carry MRS: This sight has an enclosed emitter design, which provides better protection against environmental elements like rain, dust, and debris. The EPS stands for "Enclosed Pistol Sight," emphasizing its rugged design.
- 507K: This sight has an open emitter design, which is typically lighter and less bulky than enclosed emitters.
2. Reticle Options
- EPS Carry MRS: The "MRS" stands for "Multi-Reticle System," meaning it offers multiple reticle options that can be switched between. It typically includes a 2 MOA dot, a 32 MOA circle, or a combination of both (circle-dot).
- 507K: Also features a Multi-Reticle System, offering a 2 MOA dot, a 32 MOA circle, or a combination of both.
3. Footprint and Compatibility
- EPS Carry MRS: Uses a modified K footprint, which is slightly different from the standard footprint used by some other optics. It’s designed to fit a variety of compact and subcompact pistols.
- 507K: Uses a Shield RMSc footprint, which is more commonly found on a variety of compact and subcompact pistols.
4. Battery Placement and Accessibility
- EPS Carry MRS: Typically features a side-mounted battery tray, allowing for battery changes without removing the optic from the firearm, maintaining zero.
- 507K: Usually has a bottom-mounted battery compartment, which requires removal of the optic for battery changes, potentially affecting zero.
5. Size and Weight
- EPS Carry MRS: Generally, the enclosed design makes it a bit bulkier and potentially heavier compared to open emitter designs.
- 507K: Known for being compact and lightweight, making it a preferred choice for concealed carry and compact pistols.
6. Durability and Environmental Protection
- EPS Carry MRS: The enclosed emitter design inherently provides greater durability and protection from environmental factors.
- 507K: While still robust, the open emitter design is more susceptible to obstructions from rain, dust, or debris.
7. Lens and Field of View
- EPS Carry MRS: The enclosed design may slightly restrict the field of view compared to open designs, but it compensates with better protection and durability.
- 507K: Offers a more open field of view, beneficial for quick target acquisition.
8. Price
- EPS Carry MRS: Generally, enclosed emitter designs tend to be more expensive due to their construction and durability features.
- 507K: Often priced more competitively, making it a popular choice for budget-conscious buyers without compromising on quality.
The choice between the Holosun EPS Carry MRS and the Holosun 507K depends on your specific needs. If you prioritize durability and protection against environmental factors, the EPS Carry MRS is the better option. If you prefer a lighter, more compact sight with a broader field of view, the 507K is a great choice. Both models offer versatile reticle options and are designed to enhance the shooting experience on compact and subcompact pistols.
