KEL-TEC SUB-2000 Recoil Buffer

  • Custom Molded Urethane Rubber Recoil Buffer

Reduces recoil force of bolt and overall felt recoil by roughly 30%. Proprietary Urethane Rubber Blend offers exceptional strength, durability and abrasion resistance for this specific application. Custom Molded to the exact dimensions to fit over the SUB-2000 recoil spring, inside the bolt tube, immediately in front of the hard plastic buffer (the bolt tube end plug that's part of the buttstock design). The SUB-2000 Recoil Buffer provides the necessary barrier to prevent the hard slap of the heavy bolt bottoming out at the end of travel. The cylindrical rubber recoil buffer acts like a shock absorber between the heavy blowback operation of the extended bolt and the hard plastic buffer of your SUB-2000; providing the necessary cushion and energy displacement needed to reduce the momentum and felt impact of the extended bolt onto the hard plastic buffer and ultimately your shoulder.

The KEL-TEC SUB-2000 Recoil Buffer will not affect your ability to lock the charging handle back into the notch on the bolt tube to keep your bolt open to the rear of the firearm. Designed to reduce recoil without compromising the normal function and operation of your SUB-2000! Tested by a dozen M*CARBO Brotherhood Members to ensure durability and quality results. All reported a signification reduction in felt recoil from their SUB-2000!

It's a simple 5 minute installation! Just remove buttstock and slide recoil buffer over the recoil spring. It's the KEL TEC SUB 2000 Recoil Pad for your hard plastic factory buffer.

Had some stove piping after installing.

I got the buffer and had quite a few stove pipes out of 150 rounds. I took it out and zero, none out of 150 rounds. The spring was getting hung up on the buffer, or at least that’s my guess. I installed the heavy bolt and then super glued to buffer to the plastic buffer and had one piece of brass get clipped by the bolt but no FTE or FTF. It makes a bit of a difference but the charging handle, the heavy bolt and bolt tube cover I would but first.

Sub 2000 Buffer

The buffer dropped in to my sub-2000 gen 2 as advertised. The gun was never really recoil heavy but I could tell the recoil it had all came from the hard metal to plastic contact. This rubber buffer greatly reduced the amount of felt recoil. For the price you can't go wrong.


Recoil Buffer

Easiest part to install. Don't know how well it will perform until I get to the range. Stay tune for follow up.


Well, it does what it says. Really helps lessen felt recoil

Simple solutions

MCarbo does it again. $10 and your recoil is noticeably less.
