Is there any difference between the standard M1 stock and the M1D stock?
Sounds like a silly question(s) but is/are there any differences?
Either in inletting/fitting or on how the stock was dimensioned as an M1D?
Will a M1 stock allow the M1D action to fit into it without alteration?
I know the rear hand guard is different.
Front hand guard appears the same and fits from one to the other.
