Leupold LCO - Best Overall


Why Pick This Optic - The Leupold LCO (Leupold Carbine Optic) is the optic that most people will keep think about getting for their Kriss even if they have settled with a different sight.

Perfect Aesthetics - Better looking, great overall weapon weight balance. Pimp out your KRISS Vector and kick butt on the range 

Not Miss A Thing In Your Field of View - Similar to the Trijicon MRO's large FOV. If you hate looking through a small window with tube effect, the LCO is everything opposite of that to give you fast sight picture acquisition and target transition

Save More Battery & Money - You get all the benefits from the motion activated reticle and you will actually look forward to using it without buying tons of batteries for long term use

EOTECH EXPS3-4 (BEST HOLDOVER RETICLE)

Eotech exps3 on kriss vector

Why Use The EOTech? This operator grade 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.

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 means 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

Features: 

  • Magnification: 1X
  • Objective Lens: 30 X 23 mm
  • Eye Relief: Unlimited
  • Reticle Type: 68 MOA Ring + 2 MOA Center Dot

KRISS VECTOR CQB Holdover Tips

Sight Height Over Bore Distance

From the bore to a 1/3rd co-witness height mount red dot sight is about 4 inches high.

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.

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

KRISS VECTOR HOLDOVER

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)

Increased Accuracy

The KRISS Vector is accurate up to 75 yards with a 5.5-inch barrel shooting 124gr 9mm, you can get about  10-12 inch shot group fairly easy if you dial in your optic correctly.

When its paired with a red dot sight, it will make aiming so much faster and accurate.

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 the best balance and what works for you.

Iron Sights Adjustment

In my experience, I always set up my optic with the iron sights first; then I only leave the flip-up sights up for holdover references for close-range targets.


The best way I found was adjusting the 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.

Want a even better solution?

If you have a CZ Scorpion EVO 3 front sight that you're not using, I highly recommend installing it on the Vector. It sits super low on the top rail and it's perfect for minimizing the holdover.

If you don't have a CZ Scorpion EVO, you can order these low profile sights for about $45 from CZ here.

Round-Up

Referenced Shot Show

Almost any high-quality optics will work on the Vector, but the shooter needs to be cognizant of mechanical holdover when shooting CQB.

Genreally, aim 3-4" higher over the target.


General FAQs

KRISS Vector A Practical Gun Or Just A Fun Range Toy?

KRISS Vector's design is very unique. It's the most fun on full auto mode, and the two-shot burst mode (for quick follow up shots) is also enjoyable.

The gun is very promising for its high rate of fire as the new room clearing weapon, but so far it hasn't been used in any real world military or law enforcement application.

This gun received more fame and recognition in video games and movies than it did in real life. I have seen it used more for recreational use.

Check out KRISS USA for more details here.

Using Laser Sight For Holdover Assist?

Since the holdover for the KRISS is fairly high for CQB shooting mounting a green laser sight on the full length Picatinny rail is recommended, but not necessary.

It helps the shooter get on target faster at the appropriate distance even if he/she didn't master the holdover technique.

Make sure you places the laser as close to the bore as possible and have a constant offset zero.
