Solid resin kit with metal legs and swivels. The trigger also known as the "Clacker" is solid but I might make one that works... though to what end I'm not sure. Backside of the mine. As it is, on the unfinished kit, it has the word "PRACTICE" embossed in the same font and size as the remaining nomenclature. I leave this on usually for liability reasons. This one has that wording sanded off.
