called the WM-12; it mainly differs from the USAS-12 by the lack of fixed sights and carrying handle, replaced by a Picatinny rail. The manufacturer stated that the WM-12 is not a "destructive device", and would thus be readily available to civilians. As of January 2008, however, the WM-12 was no longer to be found on Ameetec Arms online catalogs, because it was discontinued after its pre-production run. Only a few WM-12s were built using USAS-12 demilitarized shotguns.
