The Calculated Kinetics CALK DT PLT SPRGFLD ECHELON TO EPS is a precision mounting plate engineered to adapt the Holosun EPS and EPS Carry optics onto your Springfield Armory Echelon pistol. If you've invested in a modern compact red dot but your Echelon uses a different footprint, this adapter solves the compatibility problem without forcing you to buy a new optic. It's built for shooters who want to run current-generation Holosun glass on a gun that wasn't originally designed for it—whether you're training at the range, carrying for personal defense, or setting up a duty configuration.

The plate uses a modified RMSc footprint and includes full recoil lugs to handle the shock of repeated firing without creep or shift. That means your zero stays true, shot after shot. Installation is straightforward: the kit ships with all the fasteners you need, a Torx bit for secure assembly, Vibratite threadlocker to prevent vibration looseness, and a clear install card to walk you through the process. No guessing, no missing hardware trips.

One of the overlooked details that matters on a carry gun or duty pistol is co-witness capability with your iron sights. This plate preserves that ability, so you can keep your OEM backup sights in full view while running your red dot. That redundancy can matter in a critical moment. Whether you're rocking an EPS or the more compact EPS Carry, this adapter bridges the gap between your gun and modern optic technology.
