OK experts.....tell me what I have. Recently bought an L579 .308 that has the numeral 9 off center and not matching the rest of the umbers in size. The foregrip checkering is standard, however the pistol grip checkering outside space is double the size. Did the wood guy make a mistake and cover it up??? This is surely a transition gun from the L57 cause it also has a flat bottom bolt. She's a beauty and unfired. I know many of these older Sakos have anomalies, but this one takes the cake! Your thoughts please. Regards, Rick.
