Holosun EPS Full Size

The Holosun EPS Full Size is the larger version of the EPS Carry, sized for full-size and duty pistols rather than sub-compact carry guns. It is one of the only sub-$400 enclosed-emitter pistol optics with a side-loading user-serviceable battery, putting it in a different category from the SCS series (which use sealed internal rechargeable batteries).

Reticle options run the full Holosun lineup: 2 MOA dot, 6 MOA dot, or MRS multi-reticle (2 MOA dot with 32 MOA circle). The MRS variant adds a solar panel for extended runtime. CR1620 battery life is 50,000 hours at moderate brightness, with shake-awake and 12 brightness settings (10 daylight plus 2 night vision compatible).

The footprint is Holosun's K-series, a modified RMSc that the EPS Full ships with an RMR adapter plate to bridge to the dominant RMR/507C cut. This makes it a drop-in option for any RMR-cut pistol. The 7075-T6 aluminum housing is rated IPX8 for water and includes a hardened steel mounting base. For shooters who want an enclosed optic without the SCS series' integrated rechargeable battery dependency, the EPS Full Size is the right tradeoff.
