no it does not have FN stamp on the action. the only thing on the action is stamp BNP and the s number 355## it looks like it is part mauser but there is a big steel lug thats is about 1 inch long and .5 high that locks in when you close the bolt. it is a 5 digit sirese number and over the stamp BNP look like a crown this is stamped on the action and the barrel hope this helps.
