Howdy all and good day eh.So what do I have to do to my (when I receive it)M-305 to put it in a Springfield Armories M1A stock? This is a fiberglass stock (haven't received it yet either) So I guess this is all just, what if, until it (they) arrive.Read somewhere about a pin that may need to be replaced with a longer one or the stock built up. Thanks All and MERRY CHRISTMAS and a HAPPY NEW YEAR.
