I have been told if the mag is made for a bolt action by the manufacture (AIA), it is legal to own. It is irrelevant if it fits other rifles.
However in this case, if you modify that mag to fit and lock into a M14, then that maybe illegal as one would be making a mag that was outside of the manufacturer's specs. It would then fall under the magazine capacity specs.
Call before you do this, The hassle of getting caught, can cost you...
Saying that.
Imagine if Remington made a .223 / 30 rd mag for the Model 7615???
