Hi Everyone, I made a couple bolt cleaning tools to make cleaning the carbon off of the bolt tail easy. Essentially the scraper knocks off the big chunks of carbon, then the polishing arm and pad polish every last bit of carbon off in just a matter of seconds. The whole process takes about 10 seconds and does not require any solvents. Since I made the tool for myself originally I made it with the shooter in mind and tried to make it functional and a good value. Here is a picture of the tool, but for a video of how it works, visit my website www.gngtools.com or you can see it here on youtube http://www.youtube.com/watch?v=2M16c2EKFXs. Originally I made this for the .223, but knew I had to have one for my .308 so I have both calibers available. If you have both, you just need one tool and can buy the additional caliber blade so one tool cleans both rifle bolts. Thanks. Greg
