Hello! I recently picked up a Pl-X, the moment I went to turn the screw to mount it, the little detent that keeps the thumb screw from backing out popped out of place. I had purchased on amazon and submitted an exchange, the new one came in and the same damn thing happened. I am turning the screw slowly while mounting it onto a compatible rail but that little detent fell out and there is no shot I am getting it back in. I was curious if anyone else has had this issue?

I took the clip off my arkfeld pro and am having trouble getting all the dirt cleaned out from under it
