I have a Remington 700 action. I have a McMillan stock that is inletted for BDL hinged floor plate. If I wanted to use this action and stock with a factory Remington double stack detachable magazine, what do I have to do? Do the feed rails need to be milled out of the receiver? Is there going to be extensive inletting required (other than the little slot on each side for the mag release)? Anything else?
