Army, Navy, Military?  Bike builder?  Now you can show it!   


Real Decommissioned Military Caps will DEFINITELY set your Bike or Hot Rod apart from the rest.


• These caps were manufactured in the '80's from SOLID BRASS by the US Military.

• The caps have been sitting around for 30+ years, so they will have a patina to them (Please see pictures.)

• The Bung/Filler Neck is machined from Cold Rolled Steel and features a machined lip for easy installation.

• Weld in the bung at the desired height (or leave it flush.)

• The bung is machined with a groove to vent the cap.

• The retention chain is REMOVABLE if need be.

    The only thing that was better than this cap was the amazing service I received from Billet proof !
    Had a crazy deadline and they got it to me in time plus kept me up to date with shipping.
