KEL-TEC SUB-2000 Buttstock Pad Upgrade
The custom-molded KEL-TEC SUB-2000 Buttstock Pad is specifically engineered to reduce felt recoil and improve shooting comfort.
Its flat design distributes recoil evenly across the shooter’s shoulder, preventing discomfort and post-shooting marks.
The military-style pad promotes a consistent shouldering position and a more stable shooting stance, while extending the length of pull by nearly 1 inch — an ideal adjustment for many shooters.
This upgrade delivers a flatter, more controlled shooting platform for your SUB-2000, enhancing comfort, stability, and accuracy.
Designed for the longest length of pull buttstock configuration, it ensures a secure fit and improved shooting performance.
Compatible with KEL-TEC SUB-2000 Gen 2 and Gen 3 models in both 9mm and .40 Cal.
Not compatible with Gen 1 SUB-2000 versions.
What Gen is my SUB-2000?
Developed by combat veterans at M*CARBO, this buttstock pad reflects real shooter feedback and collaboration with the M*CARBO Brotherhood.
As part of a complete line of American-made KEL-TEC SUB-2000 upgrades, it delivers competition-level quality for 2nd Amendment Patriots who demand superior performance from their custom pistol caliber carbine.

Vast improvement to the factory stock.
Slightly annoying to install. Makes unlocking the carbine kind of fiddly, but still so much more ergonomic than unmodified factory stock.
Flawed
Mcarbo has been the leader in innovation for the Sub2K for some time now. I have every mod available through Mcarbo. But this buttstock pad needs to be redesigned. I don’t want to have to drill through my factory stock and have the bolts sticking out on the other side. You could have made the bolts shorter for a more uniform appearance. Also you could have provided a paper template to place over the stock to make drilling the holes easier. The more serious issue is the cutout of the pad not mirroring the factory stock at the top. The gun only folds if you have the stock pin in the first hole farthest from the back. Try to adjust it to either of the other 2 holes and the front sight runs into the pad. With this pad you basically have a fixed stock. Missouri Tactical makes a much better pad for less than half of the price, and you don’t have to drill into your stock to install it. With the new Gen 3 2K releasing it shows that people love this carbine. Hopefully MCarbo will continue to innovate. Love you guys.
Great upgrade
My installation experience: I removed the butt stock and lined up the stock and the pad in a vise with soft jaws. Used a transfer punch to mark the drill positions. Started with a smaller drill for a pilot hole, then drilled to size. If you're using a combination wrench make sure you've got the proper size. The nut is an 11/32, not a popular size, but the installation is a 10 to 15 minute job if you have the proper tools. Make sure your original drill is sharp or it will walk on you with the plastic.
KEL-TEC SUB-2000 Buttstock Pad
Pros: Way more comfortable. Sturdy. Fast Delivery.
Cons: Requires drilling mounting holes

Great addition to my sub2000. Came thru with my agenda. Very generous service answering my questions. Thank you very much. Would highly recommend you guys. Thank you for your service to our country, myself and my family.
Ease of Installation and Effectiveness
I bought these for my two (2) daughters, who each have a Sub2K Carbine. The installation was simple and the results were very well received by my girls after the installation. With a simple wood clamp, battery operated drill and screw[drive it took all of 5 minutes to install from shipping box to tightening the last screw.

Kel-Tek Sub2000 Buttstock Pad
This item is an excellent addition to the Sub2000. The installation for this buttstock was straightforward and easy to install. My only negative comment is that the buttstock is not as soft as I thought to could be. That being said, it is way better than the original hard stock and the aftermarket soft rubber stock pad that disintegrated after about a year.

What is the pad made of plastic or rubber?
What is the pad made of plastic or rubber?
i see plenty asked if work with a gen 3 sub2000 -- and your answer is yes -- but will it cover the unlock knob - your rapid deployment latch is not gen 3 usable - is this advisable to put on a gen 3 ?
Will this work with gen3 10mm
I see this fits the Gen 3 in 40 and 9mm. Should I assume that it will also fit the new 5.7x28? I would imagine the stock is the same but want to make sure before ordering.

Yes, this fits the 5.7 x 28 version.

Will this fit properly on the new Gen 3 Sub 2000? Thanks
I see that this is made exclusively for a Gen2 Sub2000. Do you have a butt stock or pad for a Gen1 Sub2000?
Thanks for your time.
No This will not fit the GEN 1
Will this work with Gen 1 40 cal ? It says it works with gen 2 but nothing about gen 1.
Have you made a version for those of us that like to use the shorter stock option? If not, would it void the warranty if I were to make the modification myself?
Thanks,
Ray
I might not have been clear with my question. I was asking about modifying the butt-pad, not the Sub2000 stock. If a relief could be molded in one end of the butt-pad, it would allow the shooter the option to adjust the stock to their preference, and, still allow for the plunger to be removed for cleaning etc.

We have not made a shorter stock, they do have 3 separate holes you can use to adjust the length. If it is still to long, I would not suggest modifying any of the parts. If it is our part you will loos the warranty, if its a Kel Tec part, you will have to call them.
Do I need to drill holes to make this pad be able to screw to my stock
Do I need to drill holes to make this pad be able to screw to my stock
Yes you need to drill small holes in to the buttstock to be able to secure the pad
Do you have to cut the buttstock pad in order to close the gun so The front sight will fit?
Hello, thank you for reaching out! No, you will just need to have it fixed into the longest position to allow it to close properly!
Hi,
I'm intersted in this butt. I can't find it in France. Can you send it to France?
