      I clean around 20-30 rifles a day and after massive carbon build up on the bolt/carrier, firing pin it requires multiple tools and cleaners to adequately clean these parts of the weapon. the new Otis Bone tool and a little cleaner makes this job as easy as turning the tool. i highly recommend this to anyone with a gas impingement rifle. well worth the money.
