Fixed with a file - Timber Creek M-Lok Quick Disconnect Mounting Point

I had the same problem as a lot of other people where the mount isn’t able to be pushed in far enough to allow the little balls in the mount to come out. File just enough material off the face of the mount to remove the finish completely and your QD will function properly and be in there solid. Not ideal but saved it from being junk. You can’t tell the finish was removed from the face when there’s a QD in there anyways
