so i just bought an Ion and At first I was having problems with after the first shot the pressure would drop off significantly and wouldn't shoot again. I'm not sure what I did (asa not all the way open ? tank all the way on ? ) but for now its staying pretty steady on the pressure gauge after each shot, But I have a hissing leak coming from the feed neck/ bolt area. Is this most likley an O-ring problem that i need to replace or something more significant ? I am running on compressed air, any help would be appriciated.

Check the orings on your bolt and inside the breech. If any are damaged, then you'll need to replace them. Also make sure to lube up your bolt with a grease based lubricant. Your regulator may need to be cleaned if you're having issues with consistent pressures. But your issue may have temporarily solved itself.

I had the same problem. I replaced the O-Rings inside the breach as well as the bolt and everything was fine.
