A genuine 30mm GAU-8 shell casing! Cannon round stands 11.25 inches tall, making it a great conversation piece! Each shell casing is purchased directly from the government and demilitarized by our company. Every shell casing is inspected and expertly refinished. The aluminum projectiles are expertly milled to exacting specifications. Although our products do not contain any active gunpowder or primers making them 100pct safe for use, they resemble live ammunition; therefore, we do not recommend bringing them to locations where live ammunition is not permitted. Not recommended for use by children 12 years and younger. Because our Shell Casings and Projectiles are made from a once-fired US Military round, they may contain minor blemishes or scratches that are consistent with their history.
