Holosun EPS Red Dot Sight 6 MOA Dot Reticle – EPS-RD-6

The Holosun EPS Red Dot Sight (SKU EPS-RD-6) is a full-size 1× enclosed emitter pistol red dot sight running a fixed 6 MOA red dot, on the Holosun K footprint with a 0.91 × 0.63 in (23.1 × 16.0 mm) window and an RMR-to-K adapter plate supplied.

The full-size EPS trades the Carry's slimness for glass — a larger window that makes the reticle easier to find under recoil and on the draw. The emitter is sealed at both ends, so rain, dust and residue cannot blank it, and the ultra-low deck height keeps a natural sight picture with iron sight co-witness on compatible slides.

How It Compares

Want a finer aiming point or switchable reticles? The Holosun EPS 2 MOA red dot sight is the precision option and the EPS red dot sight with Multi-Reticle System adds a 32 MOA circle plus Solar Failsafe. The same bold dot in green is the EPS 6 MOA green dot sight, and in gold the EPS 6 MOA gold dot sight. On a slim RMSc-cut slide, use the EPS Carry 6 MOA red dot sight instead.

Frequently Asked Questions

Is the Holosun EPS an RMSc or an RMR footprint optic?
It uses the Holosun K footprint and ships with an RMR-to-K adapter plate, so it mounts to Holosun K-cut slides directly and to RMR-cut slides through the supplied plate; it is not an RMSc-footprint optic. Our RMR vs RMSc footprint guide explains which pattern your pistol uses.

Why choose a 6 MOA dot on the Holosun EPS?
A 6 MOA dot covers about 6 inches (roughly 175 mm) at 100 yards, which makes it the fastest reticle in the EPS range to find under speed and the easiest to track between close targets.

What battery does the Holosun EPS use and how is it changed?
The Holosun EPS runs on a single CR1620 coin cell in a side-loading tray, so the battery can be swapped without taking the optic off the slide and without losing your zero. One cell gives up to 50,000 hours.

Does the EPS-RD-6 have Solar Failsafe?
No — the fixed-dot EPS-RD-6 runs on its CR1620 battery with Shake Awake motion activation. Solar Failsafe is fitted to the Multi-Reticle System versions of the EPS instead.

What is the difference between the Holosun EPS and the EPS Carry?
The full-size Holosun EPS has a 0.91 × 0.63 in window and uses the Holosun K footprint with an RMR-to-K adapter, while the EPS Carry is the narrower version built on the RMSc footprint for slim-slide pistols.

Is the Holosun EPS waterproof?
Yes — the EPS is rated IPX8 and the emitter is fully enclosed, so the dot stays visible in rain and the housing tolerates immersion.
