Yep, had/have the same issue. I believe it to be tiny amounts of lead pellet jamming the action. I replaced the bolt probe oring and striped the mag, also replacing the oring. Still had same issue. Also noticed that the bolt required slightly more force to actuate. My AW is 6 years old and never had a service (I’ve owned it from new) and having fired 4500 pellets thought it was time for a service. It’s currently with the DS factory for a full service, which I suspect will resolve the issue.
