I picked up one of these today. It was $245 OTD. Took it home and broke it down and cleaned it. Seems to fall in weight wise between a Rem 870 and a Moss. 500.
The action seems fairly smooth for bring NIB. I may have to add a better recoil pad, but I will decide on that after I take to the range next week. Here is a link. https://us.armscor.com/products/m5-shotgun
I am not too sure about the speed feed type stock and the heat shield will more than likely be coming off also.
