I just was wondering if this is necessary or if just reinforcing the fore end is all that is needed. I have a couple of stocks that I've done the carbon arrow shaft/fiberglass stiffening to and the lock up is tight on them. I just got a preban receivered M1A that was built into a Match gun (HB and unitized gasblock + other stuff) and it is in a Walnut Boyds selector cut out stock (marked Boyds in the channel) and want to use one of my glass stocks while I clean and finish the Walnut. I typically switch my 3 Now 4 GI1 M1As to glas for the winter. I am looking to maintain and possibly increase the accuracy of this rifle so that is why I'm asking, John.
