Tippman Pneumatics Model 98. Somewhere under there is a Model 98 with a Psycho Ballistics EM-98 kit which converts the gun to electro-pneumatic operation with programmable firing modes. Included on the gun is a Flatline barrel system, a "barrel extension", a bi-pod, custom stock, and a red dot sight. The gun has been "ghillied" up by Chris, who often uses a ghillie suit while playing. Check out  a review of the EM-98 kit.
