Let me quote the description: Battle Mug starts as a 13.5 pound solid block of 6061 T6 billet aluminum before it enters a state of the art CNC facility in Huntsville, Alabama. This facility produces specialized parts and equipment for the U.S. Department of Defense, major weapons manufacturers, NASA, and a host of other companies working at the U.S. Rocket and Space Center. Built to military specifications, Battle Mug features a M1913 rail interface system which allows the operator to mount a standard issue M4 carry handle, tactical light, laser device, holographic sight (we call them “beer goggles”) or even a bayonet for close quarters, high risk operations. Each individually serialized Battle Mug features Mil-Spec Type III anodizing and a crenelated base and is built with the operator in mind. Whether you are fighting drug lords deep inside the jungles of Colombia, stomping out Al Qaida terrorists in Falluja Iraq, or eradicating no-good hippies in Berkeley, California… And the price is $279.
