Add a box maganize to a Savage Model 10

CDI Precision makes excellent AICS-compatable DBMs for Savages of all flavors - long action, long action/308 mag box, short or long staggerfeed, and short or long centerfeed with top or bottom bolt release. You can send a stock to CDI to be inletted for $60 which includes return shipping, but they will drop into a Savage factory DBM inlet in a Manners and work with just a little minor stock inletting on most any stock inletted for Savage factory DBM (such as a HS Precision or Choate).

PTG also has recently started making AICS-compatable DBMs but I'm not certain about them.

Accurate-Mag also has AICS-compatable DBMs for Savage long and short action centerfeeds that supposedly fits in the Sav factory DBM inlet.

Finally, the Savage factory short action centerfeed DBM works very well, allows OALs to 3.00", and Dark Eagle Customs makes a very good 10rd magazine for it.
