Very fine as upgraded by Vollmer Manufacturing into an HK21 configured belt-fed semi-automatic rifle, retaining 95% plus original phosphate and 97% plus factory quality matte black finish, with some dried grease and limited minor handling marks. The stock is excellent with limited minor handling evidence. Mechanically excellent. The extra barrel assembly is excellent.
