The Bore-Max Speed Brush Multi-Cal Pack, Bore-Max Speed Jags & Patches Multi-Cal Pack, and the Bore-Max Speed Clean System are all designed to provide efficient and effective firearm cleaning solutions. The Speed Brush pack includes 10 popular pistol and rifle calibers with brushes that have twice the bristle density of standard ones for maximum scrubbing power; they feature stiff, nickel-plated phosphor bronze bristles that reduce chemical breakdown from solvents. Similarly, the Speed Jag and Patches pack also includes 10 popular calibers with jags and patches sized for precise bore fitment providing cleaner bores faster due to their 4X greater bore contact. Lastly, the all-in-one upgrade system – the Bore-Max Speed Clean System incorporates both these features along with a speed brush having twice the bristle density of traditional brushes; it comes with 75 speed jag patches offering up to four times more carbon and copper removal than traditional jags and square patches.
