It is an owner serviceable OU, perhaps the only one on the market. In the current EU gun regulations it makes sense. Sending a shotgun to the maker for service, repair or warranty work requires four permits, export permit, import permit, then export and another import permit for a gun which is already licensed and registered to the owner. Each permit takes time and money to obtain. The 828 lets you fit the stock, pull the action, even mess with the top rib on your own. Looks are not to my taste either, but all the people I met who bought one, like it.
