Holosun EPS RD 6MOA Enclosed Pistol Red Dot

The Holosun EPS RD 6MOA is an enclosed pistol red dot sight designed to provide a clear 6 MOA aiming dot for full-size pistols. It delivers a low-profile aiming solution while retaining compatibility with many factory iron sights.

Built for use on full-size handguns, the EPS places the emitter and optics in an enclosed housing with an ultra-low deck height to permit use of standard-height iron sights as backups on some pistol models. The sight uses a proven Holosun K-style footprint and includes an adapter plate for use with industry-standard 507C cut slides, enabling broad slide-mount compatibility.
