EOTech makes something nobody else really does: a true holographic weapon sight. Instead of a reflected red dot, an EOTech projects a laser-lit hologram of its famous 68 MOA ring with a 1 MOA center dot — a reticle that is lightning-fast with both eyes open. The EXPS and 512 holographic sights, the flip-to-side G33 magnifier, and the award-winning Vudu scopes are the core of the lineup. Here is who they are, what they make, and what is worth buying.
Who EOTech is
EOTech makes the true holographic weapon sight, projecting a laser-lit hologram of its famous 68 MOA ring with a 1 MOA dot for fast, both-eyes-open shooting. The line includes the EXPS, the 512, the G33 magnifier and Vudu scopes.
EOTech has one of the most genuinely high-tech origin stories in the gun world. The company launched its first Holographic Weapon Sight in January 1996, but its roots run back to the Environmental Research Institute of Michigan (ERIM) — a research organization spun out of the University of Michigan whose scientists worked on laser holography, synthetic aperture radar, and aircraft head-up displays. EOTech was the first company to solve the wavelength-instability problem of laser diodes well enough to build a working holographic sight, and its first units were even sold through Bushnell as the “Holosight.” The company is based in Ann Arbor, Michigan.
The history has a rocky chapter worth being honest about. In 2005 EOTech was acquired by defense giant L-3 Communications, and in 2015 L-3 settled a lawsuit for $25.6 million over “thermal drift” — point-of-aim shift in extreme cold and humid conditions. EOTech redesigned its optics to address the problem, and in 2020 the company separated from L3Harris to operate independently again. Today’s EOTech sights have addressed those issues, and the brand remains the leader in holographic sight technology. On the quality ladder it sits in the premium tier — distinctive, fast, combat-used optics with a price to match.
What EOTech makes
Holographic Weapon Sights
This is the category EOTech invented and still owns. The EXPS3 and EXPS2 are the compact, premium models favored on serious carbines (the EXPS3 adds night-vision compatibility); the 512 and 518 are the AA-battery classics; and the XPS2 and XPS3 are the small, single-CR123 options. All share the signature 68 MOA ring / 1 MOA dot reticle, a true holographic display that is exceptionally fast to pick up and works even if the front window is partly obstructed.
Magnifiers
EOTech’s G33 and G45 flip-to-side magnifiers are designed to pair with the holographic sights, giving you 3x or 5x magnification on demand that swings out of the way when you want a clear 1x view. The HWS-plus-magnifier combination is a classic, flexible carbine setup.
Vudu riflescopes
In 2016 EOTech moved into magnified glass with the Vudu line of premium riflescopes, and it landed immediately — the first 1-6×24 FFP Vudu won American Rifleman’s Optic of the Year in 2017. The line now spans low-power variables like the 1-6, 1-8, and 1-10 up to long-range 5-25 first-focal-plane scopes, plus the more value-oriented Vudu X series.
Lasers and accessories
EOTech also makes visible and IR laser aiming devices and the mounts, risers, and accessories that complete a holographic or magnified setup.
Build quality and the holographic difference
What sets EOTech apart is the technology itself. A red dot or reflex sight reflects an LED dot off a coated lens; an EOTech reconstructs a laser-illuminated hologram of the reticle floating on the target plane. The practical upshots are real: the reticle is fast with both eyes open, the large ring draws the eye quickly for close work while the center dot allows precision, and because it is a hologram you can still aim even if part of the window is blocked or broken. The housings are rugged and the premium models are night-vision compatible. After the thermal-drift episode, EOTech publicly reworked its optics and staked its reputation on fixing it. This is premium, distinctive technology — you are paying for a genuinely different and very fast sighting system, not a commodity dot.
How EOTech compares
EOTech occupies a unique spot because its core product is holographic, not a reflex red dot. Against Aimpoint (the rugged red-dot benchmark) and Trijicon, EOTech’s pitch is reticle speed and the both-eyes-open holographic display rather than the longest battery life — EOTech sights are known for shorter battery life than a typical red dot, a real trade-off for the technology. Against value brands like Holosun, EOTech counters with its distinctive holographic tech and combat use rather than feature count. In magnified glass, the Vudu line competes credibly with Vortex, Leupold, and Trijicon LPVOs. The honest summary: if you want the fastest both-eyes-open reticle and the holographic experience, EOTech is unmatched; if you prioritize maximum battery life or lowest price, a red-dot brand may suit you better.
Who should buy what
- Serious carbine builders: an EXPS3 holographic sight (night-vision capable).
- Value-minded HWS buyers: the AA-powered 512.
- Anyone wanting reach: add a G33 flip-to-side magnifier behind the sight.
- LPVO shooters: a Vudu 1-6, 1-8, or 1-10 FFP scope.
- Long-range precision: the Vudu 5-25 FFP.
If maximum battery life or lowest cost is the priority, a red-dot brand makes sense — but for the fastest both-eyes-open reticle and true holographic technology, EOTech stands alone.
The EOTech philosophy
EOTech’s whole identity is built on doing aiming differently. While the rest of the industry refined the reflected red dot, EOTech commercialized laser holography — harder to engineer, but offering a reticle that behaves in ways a dot cannot. The 68 MOA ring with a 1 MOA dot is the perfect expression of that thinking: the big ring is instantly visible for fast, close shots, while the small dot lets you reach out with precision, all in one sight picture. That speed-first, both-eyes-open design is why holographic sights earned a following among close-quarters professionals. The company’s research-lab heritage shows in everything — this is a brand that came from people solving hard optics problems, and even its hardest moment, the thermal-drift recall, ended with EOTech re-engineering the product and re-earning its place. The Vudu line extended that engineering culture into premium glass. EOTech’s bet has always been that better technology wins, and it has largely been right.
How to choose your EOTech setup
Start with the holographic sight if close-to-mid range speed is your goal. The EXPS3 is the premium pick (compact, night-vision compatible); the 512 is the budget-friendly AA-powered classic; the XPS models are the smallest. Decide whether you want a magnifier — a G33 flips a 3x lens behind the sight for reach and swings away for 1x, making one setup work close and far. If you instead want true magnified glass, move to the Vudu line: a 1-6 or 1-8 for a do-everything LPVO, a 1-10 for more reach, or the 5-25 for precision. Keep battery life in mind and carry a spare, since holographic sights draw more than a typical red dot. Match the sight to your range and your platform, and you get the fast, distinctive aiming experience that only EOTech offers.
The sight that projects a hologram
It is genuinely remarkable that a gun-sight company grew out of a University of Michigan research institute working on radar and head-up displays. That heritage produced something no competitor has matched at scale: a weapon sight that builds its reticle out of a laser hologram rather than a reflected dot. The 68 MOA ring became one of the most recognizable reticles in the shooting world, prized by close-quarters professionals for sheer speed. EOTech’s road has not been perfectly smooth — the thermal-drift settlement was a real black eye — but the company owned the problem, redesigned the optics, regained its independence in 2020, and still leads the holographic category it created. For shooters, the appeal is simple: if you want the fastest both-eyes-open reticle on the market and a sighting technology unlike anything else, EOTech is the only place to get it.
What you need to run an EOTech optic
An EOTech holographic sight is built for speed up close, and the single most common pairing is a magnifier behind it. A flip-to-side magnifier like the G33 or G43 adds roughly 3x for longer shots and swings out of the way for close work, and EOTech sizes its sights and magnifiers to co-witness so the reticle stays centered when you flip the magnifier in.
The rest is about mounting height and power. EOTech sights come on a quick-detach lever mount, so you mostly just need to set them at the right position for your eye and rifle, with backup irons co-witnessing through the window. Keep spare CR123 or AA batteries on hand depending on the model, since a holographic sight draws more than a simple red dot.
Set up with a matched magnifier and good backup sights, an EOTech is one of the fastest aiming systems made. The magnifiers, mounts and co-witness sights that pair with it are listed in the carousels below.

EOTech FAQ
Where is EOTech based?
EOTech is based in Ann Arbor, Michigan, and launched its first holographic weapon sight in 1996. Its technology traces back to the Environmental Research Institute of Michigan.
How is a holographic sight different from a red dot?
A red dot reflects an LED off a lens; an EOTech projects a laser-illuminated hologram of the reticle, which is very fast with both eyes open and still usable even if part of the window is obstructed.
What is the 68 MOA ring reticle?
EOTech’s signature reticle — a 68 MOA ring with a 1 MOA center dot. The ring draws the eye for fast close shots; the dot allows precision at distance.
What was the thermal drift issue?
In 2015, then-owner L-3 settled a $25.6 million lawsuit over point-of-aim drift in extreme cold and humidity. EOTech redesigned its optics to address it and became independent again in 2020.
What is the Vudu line?
EOTech’s premium magnified riflescopes, launched in 2016; the first 1-6×24 FFP Vudu won Optic of the Year in 2017. The line runs from 1-6 LPVOs to 5-25 long-range FFP scopes.
Do EOTech sights have short battery life?
Holographic technology draws more power than a typical red dot, so battery life is shorter — a real trade-off for the speed and reticle. Carry a spare.
Can you run a magnifier behind an EOTech?
Yes, and it is a common setup. A flip-to-side magnifier like the G33 sits behind the holographic sight to add roughly 3x magnification for longer shots, then swings out of the way for close-in work.
What tier is EOTech?
Premium — distinctive holographic technology with combat use and an Ann Arbor research-lab heritage, priced accordingly.
