I have inspected a Dumoulin action at Tradex in Canada where they sell for $495. Tradex imports them from Sarco in the states were they sell for $350. They are manufactured in China and are of poor quality compared to an Interarms. On the action I handled the floorplate latch did not function properly. They also have a dovetail system and are drilled for scope mounts. There is a post in this forum "Sarco/Dumoulin actions made in China" that I wrote.
Read what Dorleac ( a top European gunmaker) concluded after examining this action.
