I'm in the market to re-stock a M70 LA from the mid 90's. I'm looking at new stocks(McM and Manners), but I have seen a few used stocks come across. One in particular is a McM a-3 that has been pillar bedded to a M70 LA that was made in the 70's. What would I need to know if this stock would fit my barreled action and would re-bedding be a must? Thanks for input.
