So I tore the rifle apart... but before I did that... I took my torque wrench all over the rifle and found 4 loose screws.
2 of'em were on the front of the base mount
1 on the rear that keeps the rifle and stock mated

They weren't extremely loose, but when I ran the wrench through'em there was some play before it went click... It wasn't full turns/rotations, but less than a quarter of a turn for sure.

I said 4 didn't I... right? Yeah... a screw was loose in the operators head

Haven't seen my boom stick in this manner in a while.. so I took a pic.
