Spot #1: Air Source Adapter (ASA)
If air is escaping from between the ASA and your CO2 bottle, or perhaps from the tiny hole located on the underside of the ASA directly in front of the CO2 bottle, then your CO2 bottle's o-ring needs to be replaced.
Spot #2: Regulator adjustment screw

If air is escaping from the regulator's adjustment screw, do not try to force the adjustment screw in to stop the leak.
- Remove your air source and degass your marker.
- Remove the regulator's adjustment screw. Use a small flat-headed screwdriver or a straight dental pick through the adjustment screw's hole to push the small inner piston up toward the front of the reg until you can clearly see the bottom of the adjustment screw's hole.
- Replace the adjustment screw, turning all the way in until it reaches the bottom.
- Gas up your marker. Slowly back the adjustment screw out while watching the gauge. Stop turning the adjustment screw when the gauge climbs and then levels off, probably at about 800 psi if your CO2 bottle is full.
Spot #3: Gauge

If air is escaping from where the gauge's threads enter the ASA, remove the gauge using an adjustable wrench and apply Teflon tape or red Loctite to the threads and reassemble.
If air is escaping from the gauge itself, the gauge needs to be replaced.
Spot #4: Fitting threads

If air is escaping from the fitting threads, replace the o-ring on the fitting.
Spot #5: Macroline fitting

If air is escaping from the macroline fitting, replace the macroline hose and the fitting.
Spot #6: Gas-thru foregrip

If air is escaping from the point where the gas-thru foregrip threads into the vertical ASA, replace the o-ring on the gas-thru foregrip.
Spot #7: Volumizer

If air is escaping from the point where the volumizer threads into the vertical ASA, replace the o-ring on the volumizer.
Spot #8: Vertical ASA

If air is escaping from the point where the vertical ASA inserts into the main body, replace both o-rings on the vertical ASA.
Spot #9: Barrel/Vertical feed

If air is escaping from the barrel or vertical feed area, this indicates that air is leaking past the cup seal and/or main valve. Make sure you cock your bolt back into the firing position before connecting your air source.
If you have cocked your bolt back into the firing position before connecting your air source and air continues to leak, replace the cup seal and valve o-rings. If this does not solve the problem, then the entire main valve needs to be replaced also.
Spot #10: Valve stop pin

If air escapes from the point where the valve stop pin enters the main body only when the gun is fired, this is normal. Blowback air that is used to recock the hammer will exit the marker from many openings.
If air is leaking constantly, replace the cup seal and valve o-rings. If this does not solve the problem, then the entire main valve needs to be replaced also.
Spot #11: Regulator assembly

If air is escaping from the point where the two pieces of the regulator housing meet, replace both o-rings on the brass internal piston.
