If the rifle is not D stamped, is the rifle safe to fire using standard surplus ammo?
With M39 and WW2 M91 production the D chambering was standard, so many of these rifles will not have the D marking. That is due to the fact it was the standard so there was no need to mark such rifles. The only rifles that might cause a worry for lack of the D stamping would be the M91-24 and the M28-30 rifles. To be safe it is always a good idea to have the rifle checked by a gunsmith if there are any questions. Better to be safe than sorry.
