Immediate Action for a dirty bolt

The C.A.T. M4 tool is 3.5 inches long and weighs only 1.4 ounces. It is investment cast from 300 series stainless steel and then the bolt cleaning chamber is CNC machined to precisely fit a mil-spec bolt. All manufacturing is done 100% in the United States of America by American workers.

While the C.A.T.-M4 fits many bolts perfectly, due to very slight differences in bolts, the tool will fit some bolts better than others. All bolts so far encountered have been restored to "tactical tolerance" quickly. Inspection cleanliness can be quickly achieved by the addition of solvent and a patch or two.
