Description

KEL-TEC SUB-2000 Rear Tactical Folding Sights - What's Included:

  • 6061 Aircraft Grade Aluminum Sight Upright (Peep or Notch)
  • Serrated Lever with Textured Grip
  • One Carbon Steel Grip Pin and Screw
  • Two Nylon Washers for Smooth Operation
  • One 2mm Allen Key with 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!

What Gen is my 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.**

                             

Frequently Asked Questions Icon

Q: Why did you make it so you now have to manually raise it up once the gun is opened? What am I missing? Why not just make it auto pop up as the factory one does?

A: 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 sight won't fold unless you fold the SUB in half.

Just a matter of adjusting the tension properly so that it has enough friction to catch the side wall when unfolding the SUB-2000.

Q: If the rear sight is higher now how many turns to the front to make it equal? And will it stick up past the side wings of the front sight body?

A: 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.

Q: Will your sight work with the RL Rail?

A: Yes it will work with the Red Lion Rail.

This notch sight is alot better for me than the peep. Ive never been a fan of peep sights outside of basic training on an old m-16 A2. To each his own. If you do change them out,make sure you follow the video and get everything correct so the sight deploys when you unfold.

I was told the sight should pop up when the gun is unfolded and it doesn’t. I have tried everything they told me do with no success because it doesn’t work the way they told me also the notch is to tall and now all my shots are high so I would have to buy a new front sight post to get it sighted in WHY WOULDN’T IT COME WITH THE SIGHT ???? So the sight is completely useless I took it off and threw it in the trash and will never buy another one of their products again mainly because of the customer service not knowing what they should know.

I was having issues being able to see the front sight through the stick rear sight. So installed the slightly taller botched rear sight. Much easier to properly aim now, just need to make any adjustments to offset the taller rear sight on next range trip.

Easy to install. Worked with no problems. Folds as it should when carbine is folded. I would buy again if I get another version of the Sub 2000. (Currently have 40 S&W with Glock magazines).

Nice to be able to move out the way when using an optic! If your optic quit working or you just want to go old school and not use the optic you have the option to use the rear site without having to fold the rifle.
Would not auto deploy

After many attempts with different lubricants and adjustments, I finally threw up my hands and went and watched a movie. As I was watching the movie, my relaxed brain thought "You polished the other metal parts why not polish the bolt and the sides of the sight that rub against the polymer" I did and it now works like it should. I had to do some thinking so it only got 4 stars.

Question:
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.

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.
