USGI Inert 25 mm Shell Casing with Demilled Projectile

USGI Inert 25mm Shell

Own a piece of modern firepower history. This 25 mm shell casing was fired from a Bushmaster-equipped Bradley or LAV, then factory-demilled—primer struck, powder flushed, and projectile drilled—to create a completely inert 25 mm dummy round that’s safe for any collection. The aluminum alloy case mates to a steel‐body projectile with its copper driving band still intact, and each headstamp tells the story of Lake City or Olin production.

At 8 inches tall and roughly 12 ounces, it’s the perfect desk paperweight, trench-art blank, or teaching aid for ROTC and STEM classes. Quantities are small; grab a few before this brass-and-aluminum history disappears into private war rooms.
