Description

KEL-TEC SUB-2000 Rear Tactical Folding Sights (Peep or Notch)

Consists of the following components:

  1. Serrated Lever with Textured Grip
  2. Carbon Steel Grip Pin and Screw
  3. 6061 Aircraft Grade Aluminum Sight Upright (Peep or Notch)
  4. 2 - Nylon Washers for smooth operation
  5. 2mm allen key and matching set screw

Replace your stock short plastic rear sight that can't be moved and often interferes with field of view when using optics, with a Taller, Combat-Ready CNC machined 6061 Aircraft Grade Aluminum Rear Sight that will rapidly Flip Up and Fold Down. 

The Rear Sight is .060" taller than the factory rear sight with a precision machined wider aperture for faster target acquisition and improved accuracy. The Rotating Lever is Ambidextrous so it can be mounted on either side of  the rifle for both right handed and left handed shooters! Rear Sight will easily fold out of the way when using a red dot or other optics. Ambidextrous Lever Actuated Folding Rear Sights for SUB-2000 allows you to rapidly switch from Optic to Iron Sights and back again with the flick of your finger. Reliable, durable, ultra-lightweight and accurate tapered apertures in peep or notch versions. Larger .170″ peep sight aperture as compared to the original .120″ sight aperture.

Wider Peep Sight Aperture and Pistol Style Notch Sight Aperture for perfect sight picture and faster target acquisition! The larger aperture size speeds up target acquisition for close quarters combat, moving targets and low light shooting conditions. 

New Sights will Fit and Function in Both the Gen 1 and Gen 2 SUB-2000!

Folding Rear Sight is taller than the factory plastic rear sight. This sight won't interfere with the folding feature of the SUB-2000. This sight will remain folded when the SUB is unfolded. We recommend using Blue 242 Loctite on the screws to ensure tight fit during operation.

You will have to quickly re-zero and make a minor height adjustment to your front sight post. It will be well within the operating range of the factory front sight.

**We had to do away with the factory "auto pop feature" so that the sight could fold out of the way without folding the SUB-2000. The factory rear sight won't fold unless you fold the SUB2K in half. We wanted to be able to fold the sight out of the way when using a red dot. We don't advertise the new sight with the auto pop feature because it won't deploy automatically without having the screw tight enough to allow it to. If you tighten the grip pin screw enough and add loctite it will auto deploy. Just a matter of adjusting the tension properly so that it has enough friction to catch the side wall when unfolding the SUB-2000.**

Absolutely perfect
review-star review-star review-star review-star review-star
If you're a bit OG like me and prefer to run open sights, this is a must have upgrade. I had previously ordered a recoil buffer tube cover (which was greatly needed) only to discover that the thickness of the cover, combined with the shape of my face, made it almost impossible to make use of the factory rear sight. It was a no brainer to just replace the rear sight with an aluminum one from MCARBO. This sight is a little bit higher than the original, making it the perfect height with the tube cover. Installing it was a breeze thanks to the great videos put out by these guys!
Don't hesitate to buy anything from MCARBO...they will NOT leave you behind! Their followup and support has been absolutely solid!
The best upgrade for your Sub 2000
review-star review-star review-star review-star review-star
The factory sights are low which makes you rest your cheek on the receiver to get a good sight. Your cheek will feel like you spent an evening getting punched by Mike Tyson after a day at the range. The MCarbo sights fix this problem.

About that kick, get the recoil buffer, recoilless charging handle, and muzzle brake. I also bought the bolt cover which keeps my face off the metal cover. That said, the sights are easily the best upgrade as they keep you from getting beat up.

I really like the notch sight, went on easy and it just awesome . keltec should have put this sight on when they built it. great addition to my rifle. thanks i have several up grades and looks like a awesome rifle now.
Taller rear notch site should come with higher front site post
review-star review-star review-star review-star review-star
The taller notch site was easy to install per the installation video. But, in order to get the front sight post high enough to give me an 'equal height, equal light' view, as I am used to with my pistols, I had to purchase a taller front site post from another vendor. This height problem was glossed over in the install video and I think it should have been addressed by offering a taller site post and adjustment tool as part of the package if desired.

Question:
Does the tactical rear sight open when the gun is unfolded? Or does it have to be done manually?
StarShooter January 4, 2022 2:17 PM
Answers
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.
