Please excuse me if this has been answered or documented somewhere, but I am interested in acquiring a 'backup' stock for my well used L579. Is there a list of compatible stocks for rifles or is it a bit hit and miss because of how factory worked? I love the original Sako stocks and whilst I like transparency and don't want to upgrade my stock to a deluxe model, I found that they are more readily available. Any direction on what stocks may drop in and be accurate would be greatly appreciated. I can get gunsmith to work on it but most good smiths are between 6 - 8 hours away and id like to check their work. It would be handy to just drop it in should my current stock fail. As stated it's a L579 in 308 serial number range 913 - - with NO Bofors stamp. I believe this makes it a 1970 year of production?
