is it normal to feel a puff of air at the end of the shroud every shot? NOT the end the pellet comes out. the back end
I pulled the shroud off the barrel and reinstalled and tightened it. that didn't work. does the very end piece of shroud ( about as thick as a quarter) unscrew from the shroud it self? it feels like thats where the air is coming from. this gun is brand new, I'm sure AOA would let ME pay $40 to ship the gun back but.... I don't want to risk it getting damaged in shipping."zebra"Have you tried taking the shroud off and screwing back on to check it's on right with no crossed threads and on tight enough etc? might be something simple like that. If it is coming from the threaded part, maybe you could try some plumbers tape as a temporary fix until you decide what to do.
Sounds like Ernest has some good fixes if the problem is bothering you. If it's still under warranty then just ask the store you bought it from to fix it.
