Kel-Tec SUB2000 Heavy Weight Bolt Gen 1, 2

This Kel-Tec Heavy Weight Bolt is designed to replace the SUB2000 Bolt (Part #: SUB2000-152-Bolt. In some older GEN 1's: SR-152-Bolt). By replacing the standard bolt in the SUB2000 with a heavier bolt, there is less felt recoil due to the blowback design of the weapon. The heavy weight bolt weighs 14.4 ozs. Note: 1st, 2nd Gen 9mm & 40 cal, Gen 3 Glk 9mm only
