Best Way To Remove Carbon Buildup From Gas Plug & Piston Bores
Drill-type cleaning tools quickly break loose and remove hard-to-get-at carbon buildup from the gas plug and gas piston internal bores. Just insert the hardened steel scraping bit and twist back-and-forth; dual scraping edges clean in both directions. Small enough to store in a range bag or cleaning kit. Ergonomically shaped aluminum handles give you a comfortable, secure grip for maximum torquing action. Gas Plug Drill is .316" diameter for the gas plug bore. Piston Drill Set - .180" and .323" diameter drills for thorough cleaning of the piston bores.
