Holosun EPS Green Dot Sight 2 MOA Dot Reticle – EPS-GR-2

The Holosun EPS Green Dot Sight (SKU EPS-GR-2) is a full-size 1× enclosed emitter pistol green dot sight running a fixed 2 MOA green 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 bolder dot or switchable reticles? Compare the EPS 6 MOA green dot sight and the EPS green dot sight with Multi-Reticle System and Solar Failsafe. The same optic with a red reticle is the Holosun EPS 2 MOA red dot sight — our green versus red reticle comparison covers which suits which eye. For a slim RMSc-cut slide, see the EPS Carry 2 MOA green dot sight. Browse all enclosed red dot sights and Holosun pistol optics.

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 2 MOA dot on the Holosun EPS?
A 2 MOA dot covers about 2 inches (roughly 58 mm) at 100 yards, so it is the precise option in the EPS range and suits accurate shot placement at distance rather than maximum close-range speed.

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-GR-2 have Solar Failsafe?
No — the fixed-dot EPS-GR-2 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.
