Long story short. I have an Aimpoint CompM5 I bought on Black Friday on sale that I am just now getting around to. I mounted it the other day to set it up for an MPX. On/off switch is looser than normal, i.e. there is more play than any of my other units. There is also significant rattling from the back half of the battery compartment. It is not coming from anything I can see and believe it to be between the circuit board and spring I can see and the on/off switch. Given COVID and supply chain issues I know that CQ has been less than optimal with many other companies. I've never had this happen before and it is rather strange. I am concerned something important is loose. Sight turns on and is functional. Does anyone have any experience with this particular issue or is a pre indicator of an issue to come? If not that's fine but I didn't want to waste my time with CS or trying to send it back if there is nothing to be concerned about.
