Review on 🌭 610 AL Sausage Cartridge Caulking for Newborn by Mark Adams

I haven't used a bulk gun. Used cartridges only. Although it looks like metal, the handguard and the front and rear covers of the main tubes are made of polymer. The only metal parts are the stock, a small metal washer around the stock, a lock and an aluminum cylinder for the cartridge. The product description should state this so that you know the design in advance. This is NOT made in the USA. Although a little expensive.
