The Barrel Nut Wrench has machined teeth which interface with the factory barrel nut. It also has flats on the opposite side for a wrench to tighten or loosen the barrel nut. The tool is hollow and is designed to slide over the barrel. Smith & Wesson M&P 15-22 barrel nuts have been known to come loose over time, now you have the right tool for the job.
