SUB2000 Heavy Weight Bolt
This accessory 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
1st or 2nd Gen Sub 2000
