The wobble comes from the actual attaching of the can to the rifle. It seems like the spring in the 3 lug adapter is a bit weak and isn't pushing the assembly tight enough against the lugs on the barrel. Just not sure if the wobble can be ignored or if it's an issue (potential for a baffle strike). I'm used to direct thread and ASR mounts where the can does not move when it's threaded on.
Before I call the adapter manufacturer I want to make sure I'n not being OCD over a non-issue, like people who obsess over the wobble between an AR upper and lower. I don't want to be That Customer who wastes people's time over something trivial.
