Ive gotta FMP XG3S and its got some interesting marking on it, I was in hopes maybe some of you who ave put a few together might have some idea what they mean?
these ones are on the trunnion they look like little "Iron Crosses" to me

and this one on the barrel its self just looks like a squiggly, could this be a clue to what type of donor my barrel came from?
