The National Eagle machine kit comes with everything you need except for tube, grip and needle bar. Machine kits DO NOT include instructions and should only be purchased by tattooists who are well familiar with the mechanics of a tattoo machine. The National Eagle Machine Head comes assembled but without tube, grip or needle bar. The National Eagle Machine is a modified version of our Swing-Gate Machine which was designed by renowned tattooist Bob Shaw. It is also designed for easy changing of tubes and needle bars.
