FD, go to www.ar15.com and post your quastion on their discussion forum under "Rifles, uppers, lowers and more". There is a wealth of information there from the participants.
One suggestion might be to purchase an "accuwedge" from Bushmaster. It's a couple of bucks and is designed to tighten the union of the upper and lower. That may be a solution short of replacing the lower. DO NOT use the JB weld!
Get more information first. Good luck.
Oh yeah, please keep your father in law away from guns! :-)
