5. Velocity Adjustment (all models)
Always check the velocity of the marker prior to playing paintball. Different playing
fields may have different maximum velocity limits. At no time should you shoot at
velocities above 300 feet-per- second.
1. Put on an eye protective device designed specifically for paintball and make sure
that anyone within range of the Empire BT-4 Series marker does the same.
2. While pointing the marker in a safe direction, remove the barrel blocking device.
3. Point the Empire BT-4 Series marker over a chronograph that will measure the
velocity of the paintballs discharged by the marker.
4. Set the marker to “FIRE” mode (Turn Electronic Grip on or turn safety off).
5. Pull the trigger and check the reading on the chronograph.
6. Locate the velocity adjuster screw on the left side of the marker.
7. Using a 5/32" hex key, turn the screw
inward or clockwise to reduce the velocity,
and outward or counterclockwise to
increase the velocity of the paintballs
discharged from the marker (Fig. 5.1).
DO NOT REMOVE THE VELOCITY
ADJUSTMENT SCREW.
6. Electronic Grip Operation (some models)
The Electronic Grip has 3 different firing modes: Semi-Auto, Ramping, and Full-Auto.
The modes are changed by removing the left-side grip and adjusting the dip switches
located in the grip frame.
The Electronic Grip comes in Ramping mode from the factory and the Jumper in the
frame must be removed to lock the firing mode to semi-auto. The Electronic Grip has
an automatic shut-off after 1 hour of inactivity.
Activating the Electronic Grip™
To activate the electronic grip, press the ON/
OFF button on the back of the frame. A green
LED will come on to show that the electronic
grip is activated and ready to fire (Fig. 6.1).
Note: Always use name brand batteries. Using other types of batteries will affect the
marker performance.
Adjusting the Sear Height
To adjust the sear height, there is a set screw in the lower vertical arm of the sear that
contacts the front of the solenoid. If it is necessary
to raise the sear to engage the rear bolt, insert a
0.50" allen wrench past the side of trigger and
turn the allen wrench counter clockwise. Make
adjustments while the trigger frame is off the
receiver (body) and the marker is degassed. Look
down from the top of frame to help locate the set
screw. Only turn the Allen wrench 1/8 turn at a
