EoTech EXPS3-4 Holographic Hybrid Sight with G45 5X Magnifier & QD Mount - Matte Black (223 Remington Ballistic Reticle)

The EoTech EXPS3-4 holographic hybrid sight with G45 5X magnifier is a versatile optic system built for shooters who need fast target acquisition at close range and the ability to reach out to longer distances without swapping gear. This combo pairs EoTech's proven holographic technology with a flip-to-side magnifier, letting you stay on target from room-clearing distances to 600 meters. The quick-disconnect mount makes transitioning between magnified and unmagnified views intuitive—no tools, no guesswork.

The EXPS3-4 core sight runs on a single CR123 battery and delivers 1,000 hours of runtime at the nominal setting, with daylight brightness adjustable across 20 settings plus an additional 10 for Gen I through III+ night vision devices. That night vision compatibility is genuine: the optic is sealed against fog and water to 33 feet, so low-light performance holds up in the field. The 223 Remington ballistic reticle is optimized for the most common intermediate cartridge in tactical and hunting applications. Windage and elevation adjust in 0.5 MOA increments, and eye relief sits at 2.6 inches—comfortable for most shooting positions and platform setups. Weight tops out at 24 ounces system-wide, keeping your rifle's handling balanced.

Built with a Weaver/MIL-STD-1913 mounting interface, the HHS V (that's the official designation for this EXPS3-4 and G45 pairing) slides onto any standard rail system. The matte black finish is durable and won't throw glint. Your package includes the sight, magnifier, STS quick-disconnect mount, a CR123 battery, quick-start guide, and protective case—everything you need to get running immediately.

Frequently Asked Questions

Can I use the EXPS3-4 and G45 magnifier separately, or are they sold as a locked system?

The EXPS3-4 sight and G45 magnifier are paired in this HHS V kit, which includes the Switch-to-Side (STS) quick-disconnect mount. The STS mount allows you to quickly flip the magnifier out of the way without removing the sight itself, so you can run unmagnified and magnified setups without breaking down the system.

What's the effective range of this sight and magnifier combo?

EoTech markets this combination for close-quarters combat as well as 600-meter targets, reflecting the EXPS3-4's unmagnified speed and the G45's 5X magnifier capability working together.

Will this work with night vision devices?

Yes. The EXPS3-4 is night vision compatible with Gen I through Gen III+ devices and includes 10 dedicated brightness settings for NV use. The optics are also fog-resistant and sealed against moisture, supporting performance in low-light field conditions.

What battery does it use, and how long will it last?

The system runs on a single CR123 battery, which is included in the box. At the nominal brightness setting, you'll get approximately 1,000 continuous hours of runtime under standard room-temperature conditions.
