GI .50 Caliber Brass Shell Casing (Inert Dummy Round)

GI .50 Caliber Brass Shell Casing Details

Add a slice of American firepower to your desk or display case. This GI .50 caliber brass shell casing once fed an M2 Browning, the legendary "Ma Deuce" machine gun in continuous US service since the 1920s, or a Barrett anti-materiel rifle. It has been once fired, demilled, and rendered fully inert before leaving government inventory.

Features and Highlights

• Once-fired GI .50 BMG brass casing, fully demilled and inert

• Primer struck; projectile and powder removed for safe handling and display

• Mixed US headstamps: Lake City (LC), Twin Cities (TW), Remington Arms (RA), and other Cold War era arsenals

• Originally fed the M2 Browning machine gun and Barrett rifles

• Each casing carries authentic range patina that polishes to bright brass if desired

• Ideal for paperweights, trench art, display pieces, or ballistics teaching aids

• Ships within the contiguous United States only due to postal regulations on inert ordnance

• Not suitable for reloading; case mouth may show pull crimps from demill process

Headstamp variety is part of the appeal here. Each casing has its own provenance, with Cold War-era US arsenal markings that collectors and DIY craftsmen prize. Limited surplus stock; once these are gone, the lot does not refill.
