Ever heard of the GAU-8? It's a high powered gatling gun so HUGE that the US Air Force had to build a plane around it. Thus, the A-10 Warthog was born. Nothing puts fear into the heart of the enemy like 30 mm rounds at 3,900 rounds per minute. This American Made shot glass is made from a previously fired 30 mm round, and finished off with a matte black finish and our iconic Drop Line logo. Have a "round" on us!
