Safetying the Paintball Gun

[1] To safety the paintball gun:
    1. Push the Safety Pin located behind the Trigger from left to right to engage.
    2. Check that the RED ring on the Safety Pin is NOT showing.

Disengaging the Safety

[2] To disengage the safety:
    1. Push the Safety Pin located behind the Trigger from right to left to disengage.
    2. Check that the RED ring on the Safety Pin is showing.

Inserting the Barrel

[3] To insert the Barrel into the Main Body:
    1. Slide the Barrel, Nubbin on top, into the Main Body to line up the Barrel Lock Pin with the Barrel Detent Slot.
    2. Push the Barrel gently straight in until the Barrel stops moving.
    3. Turn the Barrel 1/4 turn counterclockwise to line the feed hole with the Ball Feed Tube.

Removing the Barrel

[4] To remove the Barrel from the Main Body:
    1. Turn the Barrel 1/4 turn clockwise.
    2. Pull the Barrel gently straight out of the Main Body. NOTE
      Hold the paintball gun up to prevent paintballs from falling out of the paintball gun if the Loader is still attached.

Gassing up the Paintball Gun

[5] To gas up the paintball gun:
    1. Safety the paintball gun.
    2. Hold the paintball gun upwards. Squeeze and hold the Trigger.
      WARNING
      Introducing air pressure to the paintball gun will charge and cock the system.
      CAUTION
      Do NOT use a siphon type constant air tank. Liquid CO2 will damage the seals.
    3. Attach the CO2 source to the Back Bottle Adapter by turning the Air Source clockwise.
      NOTES
      1. It is recommended to lubricate any air source O-ring with a little Lithium Grease (White Grease) before attaching the Air Source to the Back Bottle Adapter.

      2. Rotate pin valve tanks at least one full turn after initial gas up.

      3. For constant air sources with on/off valves, open the on/off valve fully.

    4. Release the Trigger.
      NOTE
      At this point, the CO2 pressure within the paintball gun will push the Trigger Rod Forward against the Trigger with a loud click.
    5. Disengage the safety.
      WARNING
      Only fire the paintball gun in areas where firing is permitted.
      WARNING
      An excessively hard trigger pull shows overpressure in the system. Do NOT fire a paintball gun that has excessive trigger pull.
    6. Dry fire the paintball gun several times in safe direction to seat the Regulator Piston and Regulator Spring Pack properly.
    7. Safety the paintball gun.

Adjusting the Velocity

[6] To adjust the velocity:
WARNING
Only fire the paintball gun in areas where firing is permitted.
WARNING
An excessively hard trigger pull shows overpressure in the system. Do NOT fire a paintball gun that has excessive trigger pull.
    1. Dry fire a few shots in a safe direction, if the paintball gun has not been fired, to seat the Regulator Piston and Regulator Spring Pack properly.
      NOTE
      To prevent paintballs from firing, either remove the Loader and empty the Ball Feed Tube and breech OR hold the paintball gun upside down with the Loader below the paintball gun and the Barrel pointed up, then shake gently to move the paintballs back into the Loader.
    2. Live fire over a chronograph to find the initial velocity.
    3. Adjust the velocity by turning the Regulator Nut with the Allen key provided. Turning clockwise will increase the velocity; turning counterclockwise will lower the velocity.
    4. Turn the Regulator Nut counterclockwise to lower the velocity if CO2 begins venting out the rear of the Regulator Nut.
    5. Repeat live firing and turning the Regulator Nut as necessary until the desired velocity is set.
      NOTES
      1. Start at a low velocity setting and screw the Regulator Nut clockwise up to the desired velocity.

      2. A complete clockwise turn of the Regulator Nut will increase the velocity from approximately 200 fps to 300 fps.

      3. If CO2 vents from the rear of the Regulator Nut, the Blow Off Valve has opened because of an overpressure. The velocity will likely be over 300 fps.

      4. Airgun Designs, Inc. has found that the best performance of the 68AUTOMAG is in the 270 to 280 fps range.

Unloading the Paintball Gun

[7] To unload the paintball gun:
    1. Safety the paintball gun.
    2. Turn the paintball gun upside down.
    3. Shake the paintball gun gently to roll all the paintballs from the breech and Ball Feed Tube into the Loader.
    4. Remove the Loader and Elbow while still holding the paintball gun upside down.
    5. Set aside the Loader and Elbow.

Degassing the Paintball Gun

[8] To de-gas the paintball gun:
    1. Safety the paintball gun.
    2. Unload the paintball gun.
    3. Unscrew the pin valve constant air tank one full turn counterclockwise or fully close the on/off valve of the on/off valve constant air tank.
    4. Disengage the safety.
      WARNING
      Only fire the paintball gun in areas where firing is permitted.
    5. Dry fire the paintball gun until the paintball gun no longer fires.
    6. If the paintball gun continues to fire, unscrew the pin valve constant air tank another full counterclockwise turn and repeat the dry firing.
    7. Repeat unscrewing the constant air tank and dry firing as necessary.
      NOTE
      Firing the last shots when degassing the paintball gun may cause bolt stick.
    8. Stop firing once the paintball gun has been degassed.
    9. Safety the paintball gun.
      CAUTION
      Tightening the Air Source back onto the paintball gun before all gas is vented from the Back Bottle Adapter will damage the Air Source O-ring.
    10. Unscrew counterclockwise the Air Source until all gas vents from the Back Bottle Adapter and the Air Source is free of the paintball gun.

Field Stripping

[9] To field strip the 68AUTOMAG:
    1. Safety the paintball gun.
    2. Unload the paintball gun.
    3. Disengage the safety.
    4. De-gas the paintball gun.
    5. Hold the rear of the Regulator and remove the Field Strip Screw.
    6. Hold the Trigger down and guide the Regulator and Valve Body back along the Rail until the Regulator Body Detent Pin reaches the stop in the Z-shaped Slot.
    7. Press down on the Air Hose to rotate the Regulator Body Detent Pin free of the Z-shaped Slot.
    8. Draw the Regulator, Valve Body and Bolt back until free of the Main Body.
Go to the next section. (Section 4)
