Couple of questions for Airforce owners
I recently purchased a Talon SS which included a CO2 adapter. This is my first Airforce rifle. I’m not positive but I believe the tophat on my CO2 adapter is missing a piece or is just broken. The gun has virtually no pressure on CO2 and sounds very strange. It appears to me that the end of the top hat is just missing completely, but I don’t really know what its supposed to look like, so I’m not sure. I can see threads in the end of the tophat and there is a rough edge where the top thread ends. I’m guessing that’s not normal either. Additionally, the breech knob has already worn two small spots down to the metal on the frame after a few hundred shots. I’m assuming that isn’t normal either, but maybe it is. This gun shoots very well on HPA, so I really don’t want send the whole thing back to AF unless its really a defect.
I’m assuming Airforce will just replace or repair the CO2 adapter, but anyone else seen anything similar?
Your thoughts on both issues greatly appreciated! Thank you, and happy New Year!

We are thinking alike. I didn’t have a guage that thick so I used a nickel which is .077″ thick and I snugged up the two small screws. I will test it tomorrow and see if that fixed it. If not, it will have to get mailed to texas.
Thanks everyone for the help! Greatly appreciated!
The set screws are used to prevent the top-hat from rotating. As stated in previous posts just snug them up, do not use excessive force for you will damage the valve stem. Use a coin to set the gap unless you have some feeler guages.
Yes, I did manually release some gas from the CO2 tank. Seems to have plenty of pressure. Tank is at 70 degrees. Its been in the house all day and my garage is heated to about 60 degrees, so no way it cooled much below 70 in the two minutes I was out there. Most likely I will end up sending it to AF for a repair or replace. One other note. The tophat will easily screw up and down with my fingers from flush with the brass valve to about a 3/16″ gap. Is it supposed to move that easily?
How about the temperture of the tank?
If too full it may lock-up like I said did you try the release of the gas from bottle.
There is just very little pressure. I just shot a pellet at a piece of plywood in the garage and the pellet just barely made a dent in the wood with the CO2 with the power cranked to 10. On HPA, power setting 4 it goes clear through the first piece of plywood and into the second one. Unfortunately I don’t have a Chrony to check the fps, but on CO2 its very low. I suppose the CO2 bottle could be nearly empty, but I just had it filled a couple of weeks ago and haven’t used it so unless its leaking it should be almost full.
Externally the CO2 adapter looks good, it is not missing any parts. Mine is set at .079″. It uses the Condor valve that is why the hole is 3x larger.
Thanks for the replies guys! I really think there is something missing from this top hat. The hole in the end is about 3X the size of the one in my HPA tank. I have not made any adjustments to the tophat on the CO2 adapter. Second pic has the side view of the CO2 top hat. Hopefully the white background will make it easier to see. Should have used that earlier.
Sometimes its the bottle on co2, I once was not getting the gas to come thru the adpter so I pushed on the pin on bottle with pliers 3 times to force out gas and to my surprise it worked the next time I screwed it on the adpter, try that. As far as wear from your cocking knob, you have to get some hard rubber or a spacer of some sort on there to stop the metal to metal contact, for along time I was using electrician tape, but it did not last long.
Good pictures for your post.
Could use a side picture of that top hat on the valve stem to show the approximate gap.
You’re used to air at a higher PSI. The CO2 stays constant at 800 PSI and should prove to be fairly stealthy.
The top hat is adjustable, should be OK at the factory setting. The wider (brim) of it should have 2 tiny set screws like on your air tank top hat. They could have looseded and the gap decreased. AF or someone else here could tell you what the gap should be.
Be careful not to overtighten and deform the thin valve stem inside the top hat.
I used a drill rod to back up thightening the set screws but one time got it in to far and really stuck. When I finally pulled it out the whole valve stem came with it. I must have looked like I had a bomb in my lap. So, I taught myself that the valve stem is easily removed from newer models.
Good luck.
I think your top hat may be set out to far and you are getting bounce back, when the hammer hit the breech slide . Also the top hat is normally adjustable.
My old Talon SS shows worn spots from the breech knob. The new Talon SS hasn’t been shot but a couple of hundred times but shows no ware as yet.
I never seen a CO2 top hat, so I can’t help you there.
