Need some help!!! I have a modlite on Arisaka side mount on my bcm rifle. Went to the range this morning and noticed the flashlight became loose from the mount while shooting. I went to remove Arisaka mount from rifle but could only get one screw loose. The other will not budge using the same Allen Wrench size. I have tried other sizes with no help. Anyone have any advice ? I don’t want to continue and end up stripping it.
