This video shows the operation of the bolt tail cleaning, notice how the CRT-15 reamer style end fits into the bolt carrier to remove the carbon inside. This is a CAD generated video, normally the two parts would be turned by hand.
The CRT-15 Carbon Removal Tool is designed to remove carbon from both the bolt carrier and bolt tail of AR family rifles. 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. (Carbon Removal Tool for AR-15, M-16, and M-4 type bolts and bolt carriers). 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.
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.
This product works great and very much worth the money
