A method for lining a gun barrel with a material selected to reduce the rate of erosion and corrosion from the rounds of ammunition fired through it includes the steps of forming a rod of the lining material, hammer -forging a barrel blank to the rod, and then drilling out a bore in the rod. The method utilizes a static mixing chamber to add the concentrate solutions to the diluent stream sufficiently in advance of one another so that adverse chemical reactions do not occur. The control unit can be instructed to control any of the discovered media players. The clothes dryer is moved towards the wall and the magnetic sheet body is moved against the metal plate.
