Made From Stainless Steel MADE IN USA CHANNEL INSTALL AND REMOVAL TOOL The Glock slide firing pin channel has a part installed in it which is called the channel liner. The channel liner is a tubular shaped plastic part that is pushed into the channel with a special tool and stays in place by way of friction fit. The purpose of the channel liner is to lessen the firing pin spring and spring cup wear and to eliminate the need for lubricant. The liner needs to be removed and replaced with a new one if it gets scored, heavily scratched or when the slide is going to be refinished in an extremely hot environment such as reblueing in a hot tank or when curing finishes in an oven. The CENTENNIAL DEFENSE SYSTEMS channel liner tool is designed to both remove and install the channel liner in the Glock slide without damaging the slide.To remove the channel liner, simply screw the threaded end of the tool into the liner, insert a Glock tool into the hole on the tool and pull the old liner out.To install a new channel liner, place the liner on the unthreaded end of the tool and push the liner into the channel as far as it will go by hand, then lightly tap the end of the tool with a plastic, wood or brass hammer until it fully seats into the channel.
