I converted my wife's ADL .243 to a BDL..... Bought the BDL stock... then got the floorplate, Mag box, spring, and new screws.... the BDL screws were supposed to be the correct ones.... but the front screw was the same for the BDL as for the ADL..... wound up ordering a longer screw and then cutting it off at the right length.... Works great and you would never know it wasn't factory!!
The parts came from Midway.... around $100 total for what all I got.... I went with the Hogue pillar block stock with the rubber over-mold so she could grip it better.
