Never before has the soldier, enthusiast, gunsmith, or armorer had access to a single tool that can remove the carbon from both the bolt tail and bolt carrier with such ease and precision. This revolutionary tool eclipses the function of the scraper style tools currently in the industry by not only improving on their ability to remove carbon buildup in the bolt carrier, but surpassing them by adding the feature of quickly and accurately removing carbon buildup from the tail of the bolt. No longer must the soldier, enthusiast, gunsmith, or armorer toil with solvent and a wire brush to adequately clean the tail of the bolt. Only the CRT-15 can remove carbon properly from any bolt tail radius, (bolt tail dimensions vary between manufacturers)! The CRT-15 is the must have cleaning tool that should be in every cleaning kit of an AR-15, M-16, and M-4 owner/operator.
