NOTE: FITS THE GEN 2 SUB-2000 ONLY (serial number on the bolt tube). DOES NOT FIT THE GEN 1 SUB-2000 (serial number on the receiver).

The Gen 2 Bolt Tube Cover is made from Santoprene, a thermoplastic elastomer that combines the best qualities of synthetic EDPM and polypropylene. It's a tough and abrasion resistant armor for your SUB-2000's bolt tube that is chemical resistant, UV sunlight resistant and ozone resistant.

Most people could install the Bolt Tube Cover in a minute or two. Simply remove the butt stock as you would to clean inside the bolt tube, and slide the Bolt Tube Cover in place. The detailed instruction sheet is included.

The Gen 2 Bolt Tube Cover is supplied full length, for the longest length of pull. There are two trim guides laser etched into the Bolt Tube Cover that can be used to trim the length of the Gen 2 Bolt Tube Cover for the mid-length or shorty length of pull. A box cutter or any sharp blade can be used to precisely cut along the trim guide. This is a permanent modification, but the SUB-2000 can still be used in any of the adjustable lengths by leaving the Bolt Tube Cover all the way forward. We recommend leaving the Bolt Tube Cover full length unless someone needs a shorter length, or if someone prefers a shorter length almost all of the time. In that case, the SUB-2000 can be extended to full length and the shortened Bolt Tube Cover does not need to be removed. It can remain in place and the SUB-2000 can be switched between the various lengths.

The Gen 2 Bolt Tube Cover has a 100% no questions asked lifetime warranty.

  • The Kel-Tec SUB-2000 carbine is fun to shoot, but the cheek weld to the steel bolt tube is a source of some discomfort. The heavy bolt recoils inside the bolt tube which is in contact with the shooter's cheek. The steel bolt tube is also a good thermal conductor, transferring heat or cold into the shooter's cheek. The Bolt Tube Cover insulates the shooter from the shock loads and temperature extremes, greatly increasing the comfort when shooting the SUB-2000.
