    This is still one of the most iconic holographic sight used in the real world, and featured in many movies and video games. The most original holographic sight product that not many companies make.

    EOTECH EXPS3-2 Review [Core Features]

    Window Size

    The broad rectangular window of the HWS enhances, rather than restricts, peripheral vision. The HWS promotes maintaining both eyes open for shooters.

    Reticle

    The EOTECH EXP3 series holosight offers a 3 reticle systems that serves shooters with long range aiming and BDC capabilities, but they are sold separately. The user can't cycle through 3 reticles using one optic

    Different reticle options have different model numbers:

    So it will be something like Eotech EXPS3-2

    68 MOA ring reticle BDC dots
    • -0 [1 MOA dot]
    • -2 [2 BDC dots]
    • -4 [4 BDC dots]

    The 1 MOA center dot with a 68 MOA ring around it is for fast combat target acquisition and precise aiming point for long range engagement without covering up too much of a standard size target.

    If you have bad eye sights, I recommend pairing the EOTECH EXPS3 with a magnifier scope to zoom in on the target and also crystalize the reticle clarity for a better aim.

    Brightness Settings

    20 Day Light & 10 NV - It's very easy and intuitive to use.

    The EOTECH EXPS3 night vision mode isn't exactly IR, but it's dimmed enough to have a crisp reticle under night vision goggle when the user presses it.

    For using a holographic sight at night, please adjust the reticle brightness to a happy medium so the glowing reticle doesn't obscure the target in low light, or filled the POV with glare even if you're using a high candela long gun light.

    Please contact EOTech for more technical questions regarding the NV mode.

    Reticle Clarity

    Most shooters out there have astigmatism will see reticle starburst if the brightness is dialed up too high.

    The holographic reticle is projected differently than an reflex red dot, and users with poor eye sight will see a blurry reticle until their vision is corrected.

    That's unfortunately the reality of using a red dot sight with poor vision.

    For this review, I worn corrective lens and I also used a camera to check the clarity of the reticle. The result is that the reticle is very crisp, and if there is anything that looks blurry it will be an eyesight problem.

    Parallax Performance

    A parallax free reflex sight is something companies often market to the users, but...

    No optic is 100% completely parallax free

    Generally the parallax shift is more noticeable when aiming at a target close up at about  5 - 7 yards.

    The further away the target is, the less noticeable parallax shift. At about 10 - 25 it's not noticeable at all

    Battery Life

    eotech exps 3 battery access open

    The EOTech EXPS3's battery life is less than 1,000 continuous hours at a standard setting 12, at room temperature, using a single CR123A battery. Compared to the 50,000+ hour red dot sight on the market, the EOTech EXPS3 doesn't quite measure up in terms of battery life because holographic laser emitter uses up the battery way faster than LED.

    Nonetheless, when you switch on or adjust the optic with the down arrow for brightness, it automatically shuts off after 4 hours. The 8/4 hour shut off is determined by the last button pressed and resets when a button is pressed again. If the battery is low or if the battery access cap isn't tightened properly, the reticle will flash to alert the user, helping with troubleshooting.

    Construction

    The construction of the EXPS3 is rock solid. 

    You can view as many images online as possible, but once you hold one in your hands close up, you will very quickly realize this thing is something you want to keep on your favorite rifle.

    The lens and light source of the optic are safely enclosed within the durable unit, and the extra hood protection cover shields it even more from recoil and rough falls.

    The front lens is made of 1/8-inch solid glass, while the rear lens is a 3/16-inch laminate glass, providing users with top-notch sturdiness.

    Moreover, the optic comes with a lens hood that covers it, giving added protection against drops and bumps.

    Mount

    The EOTech EXPS3 comes with a quick release integrated mount for fast optic attachment and detachment.

    In the case the user move optic from one receiver to another with a loose fit, the adjustable QD tension screw provides a rock solid installation in order to hold zero and prevent the optic from falling off the rifle.

    The QD mount can be removed, and the new 2023 Unity Tactical Eotech riser mount work with their FTC magnifier at the 2.26″ optic height.

    The zero repeatability based on our field testing gives us confidence. We on and off the optic on different rail slots and the zero is retained while using a magnifier.

    (We zeroed the optic at 100 yards before testing)

    There were tons of drop & torture tests done on the EOTech, so you can check them out here.

    We have seen what it can do and we want to keep it intact.

    Works with all magnifier scopes

    The mount sits just at 1/3 co-witness height, which works for most shooter providing the best cheek weld height.

    If the shooter still felt the optic mount height is short, we recommend using a mount riser to lift the optic up when using night vision goggles or other cheek weld issues.

    Adjustment

    EoTECH elevation and windage adjustment

    The EOTECH EXPS3 boasts 0.5 MOA/click adjustment knobs for elevation and windage. You can easily tweak both knobs using a flat-head screwdriver, a coin, or even a shell casing.

    Each click offers clear feedback, so you won't have to guess if you've made a proper adjustment or accidentally over-adjusted. The small ball detent ensures that each click feels distinct.

    In my experience with this specific unit, the windage turret provided better feedback than the elevation turret.

    Important to Remember : The turret direction refers to the point of impact, NOT the point of aim.

    To Buy Or Not To Buy?

    If you seek a top-quality holographic sight for a favorite rifle, the EOTech EXPS3 is among the best, making it worth saving up for.

    This pioneering sighting system has inspired many modern optics designs even though the battery life isn't the best for someone who never wants to swap battery for 5 - 7 years, but once or twice isn't too big of a deal.

    With its durability, exceptional aiming capabilities, tactical aesthetics, and proven real-world combat performance, the EOTech holographic sight is a staple in the optics world, commonly found among professional shooters.
