EOTech EXPS2-0 — Compact Holographic Sight with QD & Side Buttons — Red or Green Reticle
Overview
The EOTech EXPS2-0 is EOTech's most refined non-NV compact holographic sight: ultra-compact 96.5 mm chassis, adjustable, locking Quick-Detach (QD) lever, left-side control buttons, lower 1/3 co-witness sight height. It's the go-to reference for shooters wanting duty-grade ergonomics in the shortest possible form factor.
Available in two reticle color configurations — Red (EOTech's historic reference) or Green (enhanced daytime visibility). Select the reticle color that matches your primary use case via the selector above. Everything else — chassis, ergonomics, dimensions, mount, adjustments — is strictly identical between the two versions.
In both cases the reticle remains the legendary EOTech 68 MOA / 1 MOA: large enclosure ring for ultra-fast acquisition, 1 MOA center dot for precision out to 300 m. Choose red for all-around versatility and maximum battery life; choose green for 5× greater visibility in bright daylight and against light-colored targets.
Red or Green — How to Choose?
| Criterion | EXPS2-0 Red | EXPS2-0 GRN (Green) |
|---|---|---|
| Price (incl. VAT) | CHF 865 | CHF 1,020 |
| Reticle color | Red holographic | Green holographic |
| Bright daylight visibility | Good | ~5× superior |
| Visibility on snow / sand / light targets | Can wash out | Stays crisp |
| Low-light visibility | Excellent | Excellent |
| CR123 battery life | 1,000 hours | 600 hours |
| Eye fatigue (long sessions) | Standard | Reduced |
| Target customer | All-around shooter, mixed use | Outdoor daylight shooter |
Our Helvetia Defense recommendation: if you shoot primarily in mixed environments or indoors/covered, or if you prioritize maximum battery life, go with red. If you're mostly in full sun, in the mountains, on snow, in outdoor 3-Gun, or plains hunting, the CHF 155 premium for green is fully justified by the visibility gain.

Common Key Benefits (both variants)
- Premium EXPS ergonomics on compact chassis: ultra-short form factor (96.5 mm) meets QD lever and side buttons — the best of both worlds in non-NV.
- Adjustable, locking QD lever: tool-free mounting and dismounting in seconds, fast transfer between platforms, reliable 1 MOA zero retention after remount.
- Left-side control buttons: access controls without changing shooting position, completely frees rear real estate for a flip-to-side magnifier without conflict.
- Lower 1/3 co-witness: optimal sight height on AR-15 for co-witnessing with standard BUIS.
- Legendary 68 MOA / 1 MOA reticle: enclosure ring for instant target capture, 1 MOA dot for precision out to 300 m.
- True holographic technology: genuine EOTech holographic projection — not an LED red dot. Clear sight picture even with a partially obscured window.
- Compatible with EOTech G33/G43 magnifiers: iconic 1x/3x flip-to-side combo, purpose-designed for this optic.
- EOTech duty-grade ruggedness: CNC-machined aluminum housing, -40°C to +60°C operational range.
- 10-year warranty: EOTech manufacturer commitment with recognized after-sales support.
Green Reticle Specifics (GRN variant)
- ~5× more visible in daylight: the human eye perceives the green wavelength more efficiently. In full sun, snow, against light-colored targets, or in extreme bright environments, green stays crisp where a red dot can disappear.
- Prolonged eye comfort: the eye processes green better than red over long sessions — reduces visual fatigue during stages or training.
- Visual differentiation: on the range or in competition, the green reticle avoids confusion with other shooters' red optics.
- Trade-off: battery life reduced to 600 h (vs 1,000 h red) — the green laser requires more energy.
Use Cases & Context
- Rifle sport shooting: IPSC/USPSA, 3-Gun, PCC — both variants suit, prefer green for outdoor daylight.
- Extreme bright environments: shooting on snow, sand, full sun, glare — green variant recommended.
- AR-15 sport / premium patrol: priority platform for this optic. Ideal on DDM4 V7, DDM4 V7 K, MK18.
- Recommended magnifier combo: paired with EOTech G33 or G43 for 1x ↔ 3x flip-to-side transitions.
- Small game and predator hunting (daylight): green variant preferred in open country for reticle readability against light coats.
- Tactical shooting and CQB: instant acquisition through the 68/1 reticle in both colors.
- Multi-platform: the QD lever lets a single optic move between multiple rifles.
- Outdoor 3-Gun competition: green variant ideal for all natural lighting conditions.
- Collection / discerning shooter: both variants are in the EOTech reference lineup.
