PPU PPB556 Blank Ammo 5.56x45mmNATO 20 Per Box/100 Case
PPU manufactures many calibers of brass cased blank cartridges. Most are "full cased" which means they have an extended case shaped similar to a loaded round. This provides reliable functioning in all types of weapons. Note: A correct blank firing adapter must be used on the gun to ensure semi- or full automatic operation.
