Cleaning your AR-15
The C.A.T. M-4 Tool enables law officers with an AR system to clean their weapon and restore the bolt and carrier group to tactical tolerances in a matter of minutes. With just a few turns of the tool on your bolt, bolt carrier, and firing pin, you can take off a stunning amount of carbon and grit. Add a patch or two and some solvent to the process and your results are inspection clean in the same amount of time.
