Hello everyone: I recently purchased a Rem 760 with syn. stock. I would like to install sling swivels on the gun. I realize I need a barrel ban for the front but am wondering how thick the stock is for the back. Does a person drill the suggest 5/32 hole and srcew the stud in or do you have to remove the butt and use a stud with a nut on the inside. Thanks in advance, I don't want to make any mistakes.
