Do you want more bps and have fewer balls break in your marker while you play? Then the E-Grip Kit is exactly what you need. This kit is equipped with anti-chop technology to prevent fewer balls to break in your marker. The E-Grip Kit allows you to have the option of five different firing modes (Semi-automatic, auto-response, full auto, 3-shot burst, and turbo). To change between firing modes is as easy as a press of a button. If you have an older 98 and want to use this kit the 98 must have a serial number above 893,000. Anything below 893,000, this kit will not work and cannot be installed into the 98. Compatible with standard Non ACT marker models – Alpha Black, Alpha Black Elite, Project Salvo, Bravo one, Bravo One Elite, Tango One, Sierra One, 98 Custom, 98 Custom Pro and the 98 Custom Platinum Series.
