The EOTech HHS VI pairs the EXPS3-2 holographic weapon sight with the compact G43 3× magnifier — a factory-matched hybrid that runs a true 1× holographic sight for close-quarters speed, then flips to 3× magnification in under a second for mid-range targets. It is one of the most popular EOTech systems we dispatch from our UK warehouse, and the one that handles the widest range of jobs without compromise.
At 1×, the EXPS3-2 projects EOTech's signature 68 MOA ring with dual 1 MOA aiming dots — the large ring drives fast, both-eyes-open acquisition up close, while the secondary dot gives a quick hold-over reference at distance. Both the sight and the G43 are fully night-vision compatible, and the magnifier rides on an STS (switch-to-side) quick-detach mount so it swings clear the instant you want an unmagnified view.
How the EOTech HHS systems compare
Deciding between EOTech hybrids? The HHS VI (EXPS3-2 + G43) is the most compact 3× package. The HHS V steps up to the EXPS3-4 and larger G45 magnifier for more forgiving glass, while the HHS II pairs the EXPS2-2 with the G33 as a value-focused option. All three share the same holographic core — the difference comes down to magnifier size and reticle.

Frequently Asked Questions
Is the EOTech HHS VI night vision compatible?
Yes. The EXPS3-2 has 10 dedicated night-vision brightness settings alongside 20 daylight settings, and the G43 magnifier is rated for use behind night-vision devices.
How quickly can I switch between 1× and 3×?
The G43's switch-to-side mount lets you flip the magnifier in or out of the optical path in well under a second, one-handed and with no tools.
What battery does it use, and is it included?
A single CR123 lithium cell, which is included. The EXPS3 series runs from one centrally located battery for a low, stable mounting height.
Will it co-witness with AR-15 iron sights?
Mounted on a standard AR-15 flat-top, the EXPS3-2 sits at the popular lower-1/3 co-witness height.
How is the HHS VI different from the HHS V?
The VI uses the compact G43 magnifier; the V uses the larger G45 magnifier with the EXPS3-4 reticle. Both deliver 3× magnification — the V's larger objective gathers a little more light.
