The Custom SUB-2000 Bolt Tube Cover insulates the Shooter from repetitive shock loads while firing and environmental temperature extremes.

The KEL TEC SUB-2000 Bolt Tube Cover Protects the Shooters Face from heat and shock as well as additional wear to your SUB-2000 Receiver Bolt Tube. Solvent and Oil Resistant Custom Rubber Santoprene material will not deteriorate when exposed to gun cleaners, lubricants and solvents. To install in less than 10 minutes we recommend wiping down bolt tube with gun oil before sliding on bolt tube cover. This is a must have for KEL TEC SUB 2000 Gen 2 Accessories as it's a major advantage to reduce the shock to the shooters face as each round is fired!

The M*CARBO SUB-2000 Bolt Tube Cover will not inhibit the function of your SUB-2000. The Bolt Tube Cover will still allow the charging handle to operate normally and fully lock the bolt back in place. It's also compatible with all KEL TEC SUB 2000 Aftermarket Parts on the market for your SUB-2000. The SUB-2000 Bolt Tube Cover provides a more comfortable cheek weld on the SUB-2000 which can be difficult to obtain without the KEL TEC SUB 2000 Cheek Pad. One of the most Important KEL TEC SUB 2000 Mods you can make to improve overall performance.
