I have a manners t4a stock on remington 700 6xcand it was inletted for the bdl hinged floorplate. I was wondering what it would take to make it accept the "PTG Trigger Guard for AICS Detachable Box Magazine Remington 700 Short Action Aluminum Black" from midway usa? Would it be close to a drop in or require fitting using a mill or more like a dremel tool? The stock is currently pillar and glass bedded. Thanks for any input.
