B2K STANDARD USER MANUAL
Your B2K must be clear of all paint and any source of propellant during transportation to and
from the playing field. Keep your barrel plug in place. Keep the on-off switch in the off posi-
tion. Protect your B2K from excessive heat during transportation. Observe and obey all
local, state and federal laws concerning the transportation of paintball markers. For infor-
mation concerning any of the laws in your area, contact your nearby friendly law enforce-
ment agency.
IMPORTANT: Never carry your B2K uncased when not on a playing field. The non-playing
public and law enforcement personnel may not be able to distinguish between a paintball
marker and firearm. For your own safety and to protect the image of the sport, always carry
your B2K in a suitable marker case or in the box in which it was shipped.
If you must ship your B2K for any reason, the box in which you purchased the marker is
acceptable to all major carriers. Never ship charged CO2 or pressurized gas containers.
ADJUSTING THE TRIGGER PULL
You will notice three(3) screws in your trigger. These screws adjust the length of pull, actu-
ation point and spring tension of the trigger. The bottom screw adjusts your trigger stop point
(length of pull). The top screw is the contact point for your micro switch or actuation point.
The center screw is the spring tension adjustment screw.
1. Use blue loctite while adjusting the screws. Normal activity can cause the screws to back
out of adjustment. DO NOT glob the loctite on, it can cause damage to the micro switch
if you use too much.
2. Begin by adjusting the bottom screw to your desired pull. Screw it in to lessen the dis-
tance the trigger must travel.
3. Very Carefully screw in the top screw. Making large adjustments can force the screw into
the micro switch and damage it. You will want to screw it in to the point where it makes
contact with the micro switch but does not permanently rest on it. Continually check to
verify that the LED flashes off and then back on when you pull the trigger. If you pull the
trigger and the LED goes off and stays off, you have adjusted the screw in too far. Back
it out.
4. Adjust the spring tension by turning the screw in for more tension and out for less tension.
5. Clean up any excess loctite and let it dry for at least an hour before using your B2K. This
ensures the screws will remain in place.
B2K TUNING GUIDE
High pressure regulator adjustment:
The B2K has an innovative system. The pressurized gas is regulated internally. The pressure regula-
tor is externally adjustable via the screw in the side of the high-pressure regulator. To increase the pres-
sure use a 3/32” hex wrench inserted into the screw and turn clockwise.
NOTE: Only slight turns are needed to accomplish changes in the pressure used to shoot
the paintball.
To decrease the pressure shown on the gauge, turn the screw counter-clockwise. You must
take a clearing shot before the change in the decreasing direction can be registered.
A pressure gauge has been installed into the regulator body to indicate the exact operating
pressure of the marker. This gauge is extremely useful. At the factory we set the regulator
gauge to 180-200 PSI with an input pressure of 400 PSI using Compressed air as the base
propellant. Under normal circumstances these settings will produce paintball velocities at
approximately 280-300 fps. The input pressure from your tank should be set at 350-500 PSI.
Higher input pressures will not provide increased performance. There is a specific input side
and output side of the main input regulator. If the gauge and input sides are switched, the
outcome will be total bypassing of the main input regulator.
If you have an adjustable tank regulator, the input pressure from your tank should be set at
350-500 PSI. Higher input pressures will not provide increased performance.
If you have a fixed output regulator on your tank (pre-set) then you may have to re-adjust the
pressure shown on the gauge using the method discussed previously.
If you plan to use CO2, then please use an anti-siphon tank and a filter.
Low pressure regulator adjustment (Velocity adjustment):
The low pressure regulator is externally adjustable via the adjustment screw with the slot for
a wide screwdriver or even a quarter in the front of the low-pressure regulator. The low pres-
sure regulator is pre-set at the factory to 85-95 PSI to operate the 4-way solenoid actuated
valve. It may be necessary to re-adjust the low pressure regulator from time to time to
achieve desired velocities. Bench adjusting the regulator can be done by pressurizing the
marker, be sure the input regulator is set properly, and then turning the adjustment screw
inward (clock-wise) until you hear a leak coming from the 4-way valve in the grip area. The
4-way valve has an over-pressurization relief valve that will start to bleed off at approximate-
ly 125 PSI, once you hear the leak start then back off the adjustment screw 2 turn and the
leak will stop. That will approximate the pressure to about 90 PSI. The low pressure regu-
lator is designed to shut down and preserve the integrity of the low pressure system if it sees
an input pressure over approximately 400 PSI coming from the main input regulator. This
marker was designed with safety and safety standards in mind. If you attempt to shoot paintballs at veloc-
ities higher than established safety standards, the marker will not function properly.
NOTE 1. You may notice that if you attempt to operate the marker at extremely high veloc-
ities, the internals will not function properly!
NOTE 2. The B2K is not designed to shoot above the safety limits established by industry standards.
