Replace your stock short plastic rear sight that cannot 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 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 in 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 unless you have 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?

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.

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.

Made it to the range and sighted in. Excellent, still have problems with sight weld and Ears. Will switch to plugs. Not problem with rifle but fat cheeks and big ears.

Cons:
Very happy with the Mcarbo metal sight. From the pictures the notch sight looks to sit just a bit higher than the ghost ring sight so that is what I chose and I am happy I did. Cheek welds like any common AR now. This is how it should have come from the factory. As others have noted you can adjust the tension so it auto deploys, a nice bonus for those of us not running red dots.



I gave it 4 stars because what I really wanted was a cheap aftermarket taller rear sight. Something in the $35 range or less. I don't care about the fold down feature at all and would have been just fine with plastic. Even with 10% off this feels a little spendy for such a cheap firearm.



PS Mcarbo does 20% and free shipping pretty regularly. They also ship 10% codes with many of their products. Definitely adds up on more expensive items like this one.

Hate the stock one. The notch MCARBO makes fast point and shoot possible. With all MCARBO products, they provide excellent video instructions for installation. Now I don’t have to crush my face into the gun.

Much needed rear sight

Rating:
Pros:
Cons:
I have found the original rear sight on both my 9mm and 40SW Sub 2000 to have the aperture too low. Cranking down the front sight until it nearly disappears in the front post is still not enough to get on target; it still shoots too low. This replacement rear sight has the aperture higher, where it needs to be to get on target.

Notch sight for s2k gen2

Received the sight today and installed it in 5 minutes. Much better sight picture than factory sight. Increased height gives a much better spot weld. Haven't shot with it yet, but I know that I will shoot combat courses better and aid in faster target transition than with the smaller factory peep sight. Thanks for the rapid delivery.
