KEL-TEC SUB-2000 Gen 3 Bolt Tube Cover
Protect your face from unwanted heat, shock, and abrasions. This product ensures maximum safety and comfort, eliminating the distraction of shooting the KEL-TEC SUB-2000 Gen 3 without a cheek pad.
Built to last, the cover is made from solvent and oil-resistant custom rubber Santoprene. It remains steadfast even when exposed to gun cleaners, lubricants, and solvents. Installation is a breeze – simply wipe your bolt tube with gun oil and slide on the bolt tube cover, all within 10 minutes.
M*CARBO's innovative design ensures the Bolt Tube Cover seamlessly integrates with your SUB-2000. There's no hindrance to the operation of the charging handle, and it ensures the bolt locks back appropriately. Additionally, it pairs harmoniously with all KEL-TEC SUB-2000 aftermarket parts available for the platform.
Comfort while shooting is a given, as the cover aids in achieving a comfortable cheek weld with ease.
For those who seek custom adjustments, the cover can be modified by cutting around the provided trim lines with a sharp instrument. Laser cutouts are also provided for the serial number, charging handle operation, and trim line guidance. Do note, these adjustments are permanent.
Designed to enhance every shooter’s experience, the M*CARBO SUB-2000 Gen 3 Bolt Tube Cover acts as a formidable barrier against shock loads and temperature extremes.

Mine fits perfectly.
Mine fits perfectly. These Gen 3 M-Carbo tube covers are just a piece of rubber tubing with openings stamped in them for the charging handle and serial number. And the name M-Carbo is laser engraved (or otherwise engraved) on the side. It does not have the cutting lines on it like the Gen 2 type. The length is just right with the adjustable stock all the way back. If you need the stock closer, you will have to cut it and use the included two-sided tape, since cutting it will open the charging handle slide opening to the end of the cover. But uncut, the tape is not needed.
It's pretty nice
The tube dramatically increases the comfort of a cheek weld and it looks good. The serial number cutout is in the right spot. Unfortunately, the tube is just not the right length for a Gen3 S2000. The package indicates the part is 5.5 inches and that agrees with my tape measure. Unfortunately, that leaves about a 1/2 inch exposed on the rifle's buffer tube. None of the pictures of the Gen3 tube show this gap so it's a bit disappointing in that regard.
Don’t fit!
Even though it says gen 3 only it’s the same as one on my gen 2! If you got the stock all the way back it’ll be almost half inch short on the gen 3!

Is more product being made? Definitely excited to purchase this.
YES, they are still being made. The factory producing the design has been heavily delayed and has slowed down restocking.

Is tube cover flexible enough to apply the tape after tube cover is slipped on either modification to get max. effect of the tape? Thank you.

Good Morning,
You only need to use the tape if its going to be cut. So once cut you should be able to slip the tape underneath it for attachment.
Is this the correct bolt tube cover for the Sub-2000 CQB?
Yes - This should fit the CQB.
