KEL-TEC SUB-2000 Rear Tactical Folding Sights
Upgrade from the stock, shorter plastic rear sight that restricts your field of view, especially when using optics. Introducing our taller, combat-ready, CNC-machined rear sight made from 6061 aircraft-grade aluminum. This rear sight is .060" taller than the original and features a precision-engineered wider aperture for swift target acquisition and enhanced accuracy.
Designed for versatility, the rotating lever is ambidextrous, accommodating both right-handed and left-handed shooters. Whether you're using a red dot or other optics, this rear sight effortlessly folds out of the way. Switching between optic and iron sights is a breeze, needing just a flick of a finger.
Experience a clear sight picture with our broader peep sight aperture and pistol-style notch sight. The enhanced .170" peep sight aperture, an upgrade from the original .120", ensures quicker target acquisition, especially in close combat, moving target situations, or low-light conditions.
This sight is compatible with both Gen 1 and Gen 2 SUB-2000 models. Despite being taller than the original sight, it does not interfere with the SUB-2000's folding feature. When unfolding the SUB-2000, the sight remains folded. For a secure fit, we recommend applying Blue 242 Loctite to the screws.
A minor re-zeroing and height adjustment to your front sight post may be required after installation. This adjustment will be within the operating parameters of the stock front sight.
Please Note: The original "auto pop feature" was removed to allow the sight to fold independently of the SUB-2000 folding mechanism. While the factory sight folds only when the SUB-2000 is folded, our sight can be folded when using a red dot. The new sight doesn't have the auto pop feature to ensure user control. However, with the correct tension adjustments and the application of Loctite, the sight can deploy automatically.

Can hardly wait to get to the range.
Just installed the rear peep sight onto my Gen 2. The installation video really helped and everything fit together perfectly. One thing I noticed is that not only is the new sight higher, but the larger aperture is wide enough that I can see both wings on either side of the front sight. Now I just have to wait for a day for the Loctite to set so I can get to the range. Great job!
notch sights
I was having a problem shooting with the factory sights, these new notch sights by M Carbo made all the difference. I am able to get on target quickly.
notch sights meant for battle
these notch sights are exactly what i was looking for actually better THANKS
Notch Sight Upgrade
Great option from the peep hole sight that comes with it originally. Follow the YouTube directions and you’ll be fine.

Great upgrade on the Sub 2000
I just finished installing the rear folding notch sight for the sub 2000. The installation was easy and quick. The videos were very helpful guides to the process. I took my 9mm sub 2000 to my local range and was amazed at how much easier it was to acquire a sight picture with the taller rear sight. It was easy to shoot tighter groups and not have to struggle with the OEM sight picture.
I've made several of the internal upgrades offered through M-Carbo and this was the best one for improving the usefulness of the weapon. Thanks!

Easy install, hard to rotate
Just installed my new tactical folding sight. It is super easy to install and the videos are very easy to follow. My only challenge has been trying to get the tension just right for the sight. It seems like it is either too loose and doesn't feel like the screw is snug, or the screw it tight and the sight will hardly rotate. Once I get that perfected, it will be a 5 star. It is way easier to see and acquire the target than with the factory sights.
Big improvement over stock sights
I got the notch version. Its metal instead of plastic. Thats a plus. Went in pretty easy and had to spend a couple minutes getting the tension right. The video helped a lot. A big improvement in getting a sign picture. I used to have to scrunch my face down low tighly against the gun to get alignment. Literally a pain in the neck. Now so much easier.
Have not had my 2000 to the range yet but equipped it with a red dot site w/ side folding mount. I also removed my rear site. But I’d like to have the option to use the open sites. As this site it taller, will the upward adjustment required on the front site block my red dot as to render it useless? I realize I have to sight in the optic sight but I do not want to spend the money and time to buy the flip up site if it will. Thx
Hello. Does this sight stay in the up position while you are running the gun? I only use open sights on mine so they have to be 100% reliable. Don't mind manually flipping it up or down. Thank you.
With the added height, will this match up to a traditional popup AR style front sight? I put one on mine and it’s obviously too tall but maybe the taller rear would work. I hate the stock front sight.
I just recently bought a sub 2000 has the upgraded sight on it appears to be your product the problem I'm having is the handle is loose and comes off missing a washer also is there a way to repair it or buy a new one
Can the stock front sight still be used with either the peep or notch sight? Or will it run out of adjustment raising it to match?
Yes, you can adjust the front sight to match the rear sight.
I’ve lost the set screw for my sight. Can I buy a replacement?
I’ve lost the set screw for my sight. Can I get a replacement?
Contact us by email at Help@MCARBO.com, and we can help you.
Will this fit the 1st Gen?
Yes, it will work on any generation.
I want to use my red dot only by removing the rear and front sights. Will the 2000 function reliably without the rear sight and what can I use as a thread protector after removing the front sight? I do not want to fold the rifle. Nor do I want to string a series of regular thread protectors over the muzzle.
Does the tactical rear sight open when the gun is unfolded? Or does it have to be done manually?
It has to be done manually. This site does not pop up when you open the gun like the factory site does.
The rear sight should open and sit up automatically when you unfold the rifle, however, on occasion with a newly installed part, you may need to manually flip up the rear sight a couple times to ensure the fit is not too tight preventing it from flipping up.
