EOTECH EXPS3-4 - Best Overall

eotech exps 3 on kriss vector 9mm

Why Use The EOTech? This operator grade holographic sight for serious shooters and it's a great sight for a subgun like the Kriss Vector. It also works for most people including shooters with astigmatism.

Wide Holdover Range Adjustment - Place the reticle as close to the point of impact for high height optic over bore firearms like the KRISS Vector

Shoot With Both Eyes Open - Widen your situational awareness and not miss anything in the corner of your eye while focused on the target

CQB Holdover - Use the bottom of the 68 MOA ring for fast close range holdover to compensate CQB sight over bore offset.

Unobstructed Eyebox - Wherever the reticle appears within the window is where the bullet is going. That makes it so much easier time when shooting over barricade and around corners without perfect sight alignment.

Consistent Cheek Position - No additional riser plate needed. The reticle appears front and center for most shooters at the perfect 1/3rd co-witness height

    Common FAQ

    Sight Height Over Bore Distance

    No matter which optic you use, from the bore to a 1/3rd co-witness height mount is about 4 inches.

    What I recommend is to learn to shoot with holdover for distances within 10 yards, and find what works best for you.

    The reason you want a large range of adjustments for windage and elevation MOA adjustments is that you don't max out the elevation and still shoot low.


    Even with the included Magpul Flip-up sights, the point of impact is usually 4-5 inches low. The best CQB holdover tips are:

    • A holdover reticle helps a lot
    • Aim 2-3 inches higher for 7-10 yards
    • Adjust the front sight post all the way down
    • Adjust the rear sight up
    • Use constant offset laser sight for aiming assist (Optional)

    Best Zeroing Distance

    50 yards zero pretty good for the KRISS Vector. The point of aim is pretty much the point of impact at this distance.

    When shooting close range, 2 - 3 inches holdover is required.

    The best way is to test it for yourself and find what works for you.

    Iron Sights Adjustment

    Use a flip-up sight on the Kriss Vector for holdover reference point when shooting close-range targets.

    Adjustthe front sight post all the way down and raise the rear sight elevation all the way up to account for the holdover.

    The included Magpul MBUS rear sight doesn't have adjustable elevation to significantly shift the aim alignment down to minimize holdover.

    Based on my own experiences, even with the front sight post all the way down, I still needed to aim 2 inches higher while shooting at targets 10 yards away.

    Try This Holdover Assist

    If you have a CZ Scorpion EVO 3 front sight that you're not using, I highly recommend installing it on the Vector, so it sits lower than other front sights on the top rail for a better holdover reference point.

    Try a 9mm laser bore sight to help zeroing and practice hold over at home.

    It helps the shooter get on target faster and memorize where to hold for the KRISS Vector
