Battle Mug starts life 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 is built with the Operator in mind and features Mil-Spec Type III anodizing and a crenelated base.Whether you are fighting drug lords deep in the jungles of Colombia, stomping out Al Qaida terrorists in Fallujah Iraq, or fighting off the undead as Zombies try to eat your brain,Battle Mug is there. It's built to take abuse and will be there to offer you a frosty 24oz. reward once the mission is complete.
