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.**
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?

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.

Rear sight
I received the rear aluminum notch sight in a timely fashion. Very easy to install. Installation videos are very helpful.
Great upgrade
Really improves having to press your cheek hard against the buffer tube. Had to raise my front sights quite a bit but flawless now after adjusting. Highly recommend 👌
Still not high enough
Quality and product is great but still didn't fix the problem it said it would solve. The original rear site is extremely low but this is just about the same. I'm still way off from being able to see my front sight.
Rear slot sight
Received this sight in a timely manner. Mcarbo sent it pronto. When I installed it, the sight would not clear the handguard opening. I had to remove about 1/16" of the handguard opening material for it to barely clear. This was done without removing the handguard. I loctighted the screws with 242, set the tension and let it set 24 hrs. When I checked it the next day, the sight cleared, opened and closed right, all looked good. Then I noticed the lockup was very loose. ??this is a new gun and was no wiggle at all before this sight change. I mic'ed the original thru shaft and the sight shaft...Not that, the diameters were identical. when I checked the length, obvious the Mcarbo shaft was way short. It only came thru half the right side receiver material when squeezed. I dropped a machine screw lock washer in the cavity and replaced the thick plastic washer with the original steel one and locked it down. Perfect fit and about 1/2 of the slop was taken out of the lockup. I am happy with the sight now that it works, but I need a barrel nut wrench now to finish correcting the lockup. You should offer this as the kind people at Kel tec locktighted the nut and I can't move it. If I didn't have a stigmatism, I would switch it back. but alas, the original sight will do me no good at all.
Notched open sight
The sight picture was dramatically improved with the addition of the notched rear sight. Quick acquisition, better cheek weld, I highly recommend this addition prior to adding a red dot. You may not even need a red dot.
Another needed addition.
I've added just about all the Mcarbo pieces to my sub . This rear sight was probably the last thing I think I'll need. And it did get my head up from the tube. Every part I put in has fit perfectly, and has been an improvement. Not only in the way it functions, but it is also more comfortable when I run it. And I appreciate the fact that there is a video showing how to replace the factory part.
Solid Part. Peep better than slot.
Installed the slot sight and found it to be difficult to position the rear sight half way down the front sights. NOT like a handgun. I emailed M*CARBO support and asked for an exchange for the peep version. No problem. Sent slot sight in and promptly they sent the peep sight. Went on the gun as designed. The folding feature is a great upgrade over the stock plastic rear sight. Another quality M*CARBO product.
Much better than stock
Sub 2000: cool weapon, but I hate plastic parts when not appropriate.
M*Carbo: cool company. Helps me get rid of the inappropriate plastic parts.
M*Carbo Installation Videos: very informative, perfect demonstration, very amusing/entertaining.
Very easy install with the great video.
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?
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.
