the muzzle of the marker; three bolts must be loosened before the barrel can be removed. The Flatline is often favored by players who like to play farther back roles, especially those providing suppressive fire as the range gives them an advantage. E-Grip The E-Grip is an aftermarket pistol grip and trigger for the Tippmann A5, though the model A-5 with E-Grip can be bought directly from Tippmann. There are two types of electronic triggers now available. There is the older and significantly harder to find Tippmann produced E-Grip. It features five different fire selections which include: Semi-automatic fire Full-automatic fire 3-round burst fire Turbo fire Auto-response fire The maximum firing rate of the E-Grip is 20 balls per second. Firing modes are very easily selected by means of a screw which is rotated to toggle modes. Maximum rate of fire can also be changed via another screw on the grip frame. There is also the newer E-Grip produced by Wicked Air Sports (W.A.S.). This is what is commonly sold now by Tippmann in their E-Grip package. This trigger will also be installed an all A-5 markers ordered with the E-Grip installed. Firing modes on the W.A.S. trigger are: Semi automatic Three shot ramping Three shot full auto Auto-response Turbo The "Three" in the "Three Shot Ramping" and "Three Shot Full Auto" programming modes refers to the trigger needing to be pulled three times before the full auto or ramping are activated. The first three shots in this will be semi automatic. This makes the trigger legal for certain competitions. Programming the W.A.S. trigger is more difficult. There is a menu system that is controlled by the pressing both trigger and a small button on the front of the grip that can only be pressed with a tool. There is a small three color LED that outputs data by different patterns of blinking and LED color. The trigger can be programmed more deeply than the older Tippmann E-Grip. Maximum firing rate is 30 balls-per-second but is usually programmed much lower. Dwell and Debounce is also programmable. The W.A.S. board is also used in the Tippmann 98 line of paintball markers. However the polarity of the microswitch is reversed. Polarity can be changed by referring to the owners manual. The same board can be used in both markers.
