Factors to Consider When Choosing The Best Red Dot with RMSc Footprint
- Reticle Size and Type
Red dots with an RMSc footprint come with different reticle options. Some models, like the Holosun HS407K-X2, feature a simple 6 MOA dot, ideal for fast target acquisition. Others, like the Holosun HS507K-X2 and EPS Carry, offer multi-reticle systems, allowing users to switch between a 2 MOA dot, 32 MOA circle, or both for added versatility. Choosing the right reticle depends on your shooting preference and intended use.
- Enclosed vs. Open Emitter Design
Open-emitter designs, like the Vortex Defender-CCW, are lightweight and offer a clear-sight picture, but they are more susceptible to dust and debris. Enclosed models, such as the Holosun EPS Carry, provide better protection from environmental elements, making them more reliable for everyday carry and duty use.
- Durability and Build Quality
Most high-end RMSc red dots are made from 7075-T6 aluminum or aircraft-grade aluminum, ensuring shockproof performance. The Leupold DeltaPoint Pro is battle-tested with a rugged housing, while Holosun and Vortex models offer scratch-resistant lens coatings for added protection.
- Mounting Compatibility
While all these red dots use the RMSc footprint, some models may require an adapter plate for specific pistol slides. Always verify compatibility with your firearm, especially if you own a Glock 43X MOS, Springfield Hellcat, or SIG P365.
- Battery Life and Power Features
A long battery life is crucial for a reliable red dot. Holosun models use Shake Awake technology to conserve power, with some offering solar backup, while the Leupold DeltaPoint Pro features Motion-Sensing Technology (MST) to extend battery life. The Vortex Defender-CCW provides up to 9,500 hours of continuous use.
- Brightness and Night Vision Compatibility
Adjustable brightness settings are important for different lighting conditions. The Vortex Defender-CCW and Holosun models offer multiple brightness levels, including night vision compatibility, ensuring clear visibility in any scenario.
