    I\'ve added a polymer ring at the end of the freeloat rail (white color) to bring the outer barrel to the center. Applied insulation tape on the precision barrel to minimize the vibration in the outer barrel. Applied Teflon tape on the Hop up rubber and Cylinder head for a better seal. Used silicone oil in the Cylinder and Nozzle for a better seal. on the gears i used silicon grease for smoother operation.
