Dont think so Peter. The seer fouls even with no wood on it. Looking at my no4 mk2 I can see the seer looks a noticable amount higher, it woud be a big chisel mark to correct that. The "forged" serial number on the bolt is enough for me to return it I think, I mean if its got these 2 nasties what else is there. If I'd paid only a little I'd strip it for parts, as I need a good barrel but a $700 loss I can ill afford.
