An ACT enabled markers contains an exclusive new Anti-Chop Technology, a patent pending design to help eliminate ball chopping and ensure consistent performance. Using a new technology that has the front and rear bolt working independently of each other, ACT virtually eliminates ball chopping and improves ball accuracy with less barrel cleaning; and unlike other anti-chop systems, the system maintains consistent ball velocity shot after shot and does not have to be re-cocked if the anti-chop technology had to be engaged. Fits Alpha Black, Project Salvo and Carver One. Also will work to upgrade a 98 Platinum Series NON-ACT to ACT. Will NOT work on 98 custom or custom pro. Includes all the parts need for a functioning ACT Bolt system.
