The Holosun EPS Red Dot Sight (SKU EPS-RD-2) is a full-size 1× enclosed emitter pistol red dot sight with a fixed 2 MOA red dot, a 0.91 × 0.63 in (23.1 × 16.0 mm) window and the Holosun K footprint, supplied with an RMR-to-K adapter plate.
The full-size EPS trades the Carry's slimness for glass — a noticeably larger window that makes the dot easier to find under recoil and on the draw. The emitter is sealed at both ends, so rain, dust and residue cannot blank the dot, and the ultra-low deck height keeps a natural sight picture with iron sight co-witness on compatible slides.
How it compares
Want a faster dot or switchable reticles? Compare the Holosun EPS 6 MOA red dot sight and the EPS red dot sight with Multi-Reticle System and Solar Failsafe. Prefer a green reticle for contrast against foliage? The Holosun EPS green dot sight with a 2 MOA dot is the same optic with a green reticle — our green versus red reticle guide covers the trade-off. On a slim RMSc-cut slide, the EPS Carry red dot sight with a 2 MOA dot is the compact equivalent. Browse all enclosed red dot sights or read the Holosun range buyer's guide.
Ideal for
- Section 1 long-barrelled pistols and licensed revolvers on K-cut or RMR-cut mounting
- Airsoft gas blowback builds where a larger window speeds up target acquisition
- Pistol-calibre carbines and rimfire .22 LR pistols and carbines
- Practical shotgun and 3-Gun competitors wanting a big, sealed window

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, which means 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.
What is the difference between the Holosun EPS and the EPS Carry?
The full-size Holosun EPS has a larger 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.
What is the click value on the EPS-RD-2?
Windage and elevation adjust in 1.5 MOA per click increments.
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.
