Hey guys, I'm trying to get my Bulgarian (russian remarked) RPK74 build finished up. It's definitely an old russian gun that had the trunnion milled down and remarked with the Circle 10. I have 2 questions, if it's a 1988 kit, it should have the squared off DIMPLED trigger guard? It's my understanding that around 1985 is when they switched from the smooth to the dimpled Trigger Guard's. Can anyone help confirm that. Also, if it was originally a Russian Built RPK74 and the trunnion was remarked Bulgarian, would the selector lever markings have stayed the original Russian AB/OA? Thanks in advance for any assistance you can offer.
