Best Enclosed Emitter Red Dots: Holosun EPS vs Aimpoint ACRO

Enclosed emitter red dots are the future of pistol optics. We compare the Holosun EPS Carry, EPS, and Aimpoint ACRO P-2 to find the best sealed red dot.

Why Enclosed Emitter Matters

Traditional open-emitter red dots have an exposed lens that can collect debris, rain, and lint — especially when carried concealed. Enclosed emitter designs seal the entire optical path, making them far more reliable for daily carry and duty use.

The Contenders

Aimpoint ACRO P-2 — $599

The original enclosed emitter pistol optic. Aimpoint build quality, 50,000-hour battery life, and ACRO footprint. The downside is the premium price and proprietary mounting footprint that requires specific slides or adapter plates.

Holosun EPS Carry — $399

Holosun's answer to the ACRO. Uses the popular Shield RMSc footprint, making it compatible with most micro-cut slides. Multi-reticle system, solar backup, and shake-awake at a lower price. Our top pick for most shooters.

Holosun EPS (Full Size) — $419

Larger window than the EPS Carry, using the Holosun K footprint. Better for competition and full-size duty guns where the extra width is not an issue.

Our Recommendation

The Holosun EPS Carry is the best enclosed emitter red dot for most shooters in 2026. It combines the reliability of a sealed design with the compatibility of the RMSc footprint and Holosun's excellent feature set.
