I've come across some info that indicates the prefixes tie the serial number to 1/2 a decade (A was early 70's, B was late 70's early 80's, C was late 80's etc.) I'm trying to uncover what block of time or serial numbers were tied to the specific prefix, along with if that change meant a change or upgrade in factory equipment, or whatever.
I understand how to date the barrels and that typically, the older Dupont era guns typically get a thumbs up time and time again and that the later rifles seem to have a reputation for poor fit and finish, and accuracy maybe not as good as it once was, but I know of guys that have Sendero rifles and of one 223 VTR that shoot incredible.
