    300 feet per second). Depending on what modes of fire are allowed at the field where you are playing (semi-automatic, rebound, etc.) you may need to adjust the G-1 ’s firing mode. See the Electronic Adjustment section for more information.

    This DOES NOT mean that you should neglect your G-1 . If PROPELLANT: or Nitrogen/Compressed air you take care of it off the field, your G-1 RATE OF FIRE: 11 bps will take care of you on the field. For best OPERATION:...
  • Page 5: Barrel Blocker / Hopper

    Its low-force bolt will often prevent paintballs from being chopped if the hopper is not able to load paintballs as fast as the G-1 being fired. If you want to realize the G-1 ’s maximum firepower potential, especially if it is upgraded...
  • Page 6: Gasses

    Always turn-on or screw-in a compressed air system or CO slowly, so that the valve opens slowly, and the gas pressure inside the marker is raised smoothly. Be gentle to the internals of your G-1 and they will reward you with a long service life.
  • Page 7 J-shaped tube that draws gaseous CO from the top of the tank when it is in a horizontal position. Anti-siphon tubes must be professionally installed, to ensure that critical safety checks are performed during valve installation. If using an anti-siphon tank, the G-1 ’s IMPORTANT stock bottom-line ASA fitting should be replaced with an ASA that will place the tank completely hori- zontal.
  • Page 8: Battery

    The G-1 is powered by a standard 9-volt alkaline battery. Lower cost “heavy duty” batteries will not consistently deliver the amperage needed to operate the G-1 . Erratic performance, especially drops in velocity or skipped shots during rapid fire can result from a battery that is not delivering full power.
  • Page 9: Paint

    If velocity adjustment is necessary, Use a 5/32-inch allen wrench on the adjuster in the bottom of the vertical regulator, turn clockwise to increase the velocity/pressure, and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the gas pressure inside the G-1 to stabilize.

    FIG. 8 TRIGGER ADJUSTMENT The length of the G-1 trigger pull is adjustable with a 1/8-inch allen wrench. The trigger adjustment screw is located at the bottom of the trigger guard where it meets the grip frame. It may be helpful to remove the marker’s rubber grips to provide easier access when making adjustments.

    . If you intend to use HPA, you must change your dwell mode in order to achieve best gas efficiency and battery life. With the marker unloaded and de-gassed, remove and unplug the 9-volt alkaline battery. Plug the battery back in while holding the power button down. The G-1 will indicate that it has changed to HPA mode by double-blinking the power button LED and turning off.

    BEFORE PERFORMING MAINTENANCE PROCEDURES. Dry-fire 2 or 3 shots in a safe direction to ensure that no paintballs remain in the G-1 Continue to dry fire the G-1 in a safe direction while turning off or unscrewing the HPA system or CO tank, until all of the gas pressure inside has been released.

    Slide the bolt stop onto the bolt from the rear. Slide the rear of the bolt into the bolt sleeve. Hold this entire assembly vertically with the front of the bolt pointing upward, and insert it up into the back of the G-1 .

    Reach the long end of a 1/8-inch allen wrench through the access hole in the top tactical rail, down into the head of the vertical ASA screw. Unscrew the the two gas-through banjo bolts (indicated with arrows in Figure 15) using a 1/8-inch allen wrench. If the G-1...
  • Page 16: Feedneck Position

    Both rubber ball detents should extend into the breech and show no rips or tears. If they must be replaced, they may be pried out with an o-ring pick, and pressed into place with a small allen wrench. If the G-1 has been upgraded with a circuit board featuring an anti-chop eye, holding the breech and receiver upside down will help the anti-chop circuit board remain seated while the parts are being reassembled.
  • Page 17 To change the side from which the G-1 feeds, the marker must be disassembled and the breech removed from the receiver, following the directions for advanced maintenance.
  • Page 18: Vertical Regulator

    FIG. 19 REGULATOR DISASSEMBLY REGULATOR SERVICE Although explained here, regulator service should only be performed by a GOG Paintball trained airsmith. With the marker unloaded and de-gassed, remove the lower tactical rail as when installing a flashlight (see flashlight section of this manual). Unscrew the regulator from the marker and remove the grip frame following the instructions in this manual.

The vertical regulator is reassembled in the reverse order of disassembly. The piston slides into the regulator body wide end first, followed by the regulator spring.
