I have a Rem mod. 7 that I bought off Gunbroker. It looks as though someone got out their D4000 Dremel, and tried to grind a portion of the rails out of it. Totally worthless as far as feeding properly. So i'm thinking my only recourse if I want to save the action is to mill the rails to accept a DM. Would someone have some pics of the rails on a factory 700 DM, so I have at least some idea of where I need to go with this....or some dimensions fore and aft in the magazine cutout. I have a standard factory 700SA magazine, and want to keep it the same as factory DM's.
