Pro-Shot German Series HD Nylon Bore Brush Features The Pro-Shot German Series HD Nylon Bore Brush uses heavy-duty nylon bristles instead of traditional bronze giving shooters a brush that can be used more frequently without concern over excessive bore wear. Sized specifically for .308 caliber and 7.62mm rifles the brush maintains full bristle contact with the rifling as it travels the length of the bore. That consistent contact helps clear fouling and buildup thoroughly on every pass. The nylon construction also resists corrosion making it a durable choice for regular range use. Pro-Shot s German Series brushes are built to a heavier-duty standard than standard nylon brushes giving them a longer service life under repeated cleaning. This brush works with standard cleaning rods fitting easily into an existing cleaning routine for .308 and 7.62mm rifle owners. Choosing a nylon brush over bronze is a common preference among shooters who clean frequently and want to minimize bore wear over time. This brush delivers that durability without sacrificing cleaning performance.
