Where can i purchase the threaded part that goes into the gun and punctures the co2 this is my second request

Yes there is an "O" ring seal that is supposed to be there.

I have the same problem and have dealt with guns for 40 years !
I am glad to see that the other folks have some realistic and innovative ideas of how to remedy this problem.
I went to Lowe\'s on a "tip" and found some very small \'O\' Rings for $ 0.87 for two and I am experimenting with them. The first try I couldn\'t crank the screw down far enough to even puncture the CO2 Cartidge. Using a larger screwdriver I finally managed to puncture the cartidge, unfortunately it still leaked but waas a much smaller leak.

Still experimenting.

I am going on-line to locate the Model 380 Schematic diagram which is where I ran int this site.

Good luck all !

Hi,
There is a seal that goes over the end to hold the pressure after the puncture.... that is missing.

The Phantom Break-Barrel does not use CO2. It is a spring-loaded break-barrel weapon. If you really do have a CO2 gun, check the rubber seal around the outside of the cartridge puncture needle.

I have an pro77 co2 bb gun.for some reason when I pull the the trigger
the hammer won't deploy.can you help me fix the problem........

I would send it of to fix, playing with compressed gas is dangerous, sound like a seal my have corroded.

You should be able to remove the left side grip, unscrew the bolt on the bottom of the grip, insert co2, and then tighten bolt to puncture cartridge. Hope this helps

the gasket on the gun is probably bad

Could possibly be simply the time it takes to pierce the seal until it actually seats itself on the gasket. I usually wind up the screw until it is ready to puncture the seal and then I wind up for a quick twist in order to make it seat quicker.
