Leupold LCO

Why LCO looks so good on the KRISS - The Leupold LCO (Leupold Carbine Optic) is the most unique compact red dot optic that looks and works great on the KRISS VECTOR and it's something different than an EOTECH.

While the market is filled with legacy sights, but the Leupold has made a unique offering of their own, to set themselves apart from the competition.

The sight weighs about the same like other optics (9.5 oz), and the best part about it is the unique look and experience on the KRISS than with EOTECH, which means 32mm big aperture for large field of view, and way longer battery life.

Also features motion activated reticle for battery saving

What people are saying about the LCO - The only spec we wish it has is to a 65 MOA ring like the EOTech for better holdover reticle for distance shooting.

Eotech exps3 on kriss vector

EOTech is the world leader for making holographic sights. Over millions of units are sold to military and law enforcement around the globe to combat terrorism and other threats.

Why we picked this optic - For CQB sub-gun usage, The 65 MOA ring with a ballistic compensator is great for instantly placing the reticle on the target while shooting on the move or transitioning.

Since the optic sits about 1/3 co-witness on the Vector, you absolutely need to take full advantage of the 65 MOA ring reticle for easier & faster CQB holdover.

To case a point, the EOTech sets the measuring stick for other optics like the Holosun to have similar features.

What do people say about the EOTECH - Pretty much everyone says it's the most trusted holographic sight you can buy, and it's the most popular sight for tactical carbines and PCC. 

They're the first company to lead the industry on holographic aiming solution and their products are seen all over the world in the hands of the special forces, SWAT, civilians, movies and video games.

Holosun 503gu

Affordable Alternative An Aimpoint Micro - For Aimpoint Micro lovers who can’t afford the optic, here is the good news. The Holosun 503GU is a best Aimpoint Micro alternative with similar durability & even way longer battery life by 2X – 100,000 hours.

Holosun has been a disruptor in the red dot industry for making high strength, lightweight optic that feels just like an Aimpoint Micro.

How Does It Compare To An Aimpoint - The Holosun 503GU has similar body profile and the feel as the Aimpoint Micro, and it also has the same mounting footprint to accept any Aimpoint Micro aftermarket mounts. 

Something the Aimpoint doesn't have is the ability to switch between 2 MOA center dot to a 2 MOA dot inside a 65 MOA reticle ring, which is an awesome feature for transitioning between CQB & medium range on the go without swapping optics.

It works great and holds zero on most small bore rifle and pistol carbines.

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.


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 the point of impact.

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.

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.
