If the stock doesn't have the receiver serial # stamp on it or any other stampings to identify it to the iron then you can try finding one thru the military surplas sites aka Sarco, Numerich Arms. If you decide to repair the crack then I suggest Brownells Acraglass over wood glue and other retail store bought items. The Acraglass will hold for a life time and under harsher extremes than wood and super glues will do. http://www.brownells.com/gunsmith-t...bedding-adhesives/acraglas-gel--prod1038.aspxGreat advice and info. Chief your first fix method with the pins seems the most secure. The glue/clamp method may work with less effort. The crack is only one side and goes from the back to the middle of the magazine area, where it stops. Here is a pic a bit closer of the most noticeable part with strong top light.
