.50 Caliber BMG Keychain

This is a multi-part assembly of a .50 caliber BMG round made into a wearable keychain or necklace. It is scaled down 60% from true size, as a full-sized round is too big to be worn. Inside of the round is hollowed out and acts as a secret compartment. All parts are engineered with threads and should mate nicely.

Length: 82mm
