If you've ever used one of the shield red dots with the direct mount co-witness, this holosun design looks real promising. It fixes the open emitter vulnerability issue but wisely keeps the co-witness option for pistols with it's footprint.
The EPS-RD-MRS is a full-sized, enclosed handgun sight featuring an aspheric lens for a perfectly clear sight picture. EPS-RD- MRS has an ultra-low dot height for compatibility with most factory iron sights and utilizes Holosun’s proven K footprint.
What is the Holosun K series footprint?
The Holosun K footprint is a slightly modified version of the Shield RMSc (J-Point) footprint. The mounting holes between the two footprints are identical meaning that optics cut for the Shield RMSc footprint will allow any Holosun K footprint optic to line up with the mounting holes.Dec 20, 2022
