Hi guys I'm new here, just looking for some info on this rifle we found discarded by a tenant from the property we leased out. Did some basic research but not found much - just that the rifle seems to be of japanese make and the scope may or may not be an airsoft scope.

Would appreciate any help on this one - particularly if either of these items are worth anything. Does it take 6mm or 8mm rounds? I'm aware that the rifle is missing a magazine and if that needs replacing, where I could find a replacement that actually fits - not sure if the manufacturer sells them individually.

Thanks.
