Real expended shell casing is not included.

Fitment With Expended 40mm Casings

The topper is designed to fit expended 40mm shell casings.

Because fired casings can vary slightly due to manufacturing tolerances and heat expansion during firing, individual fit may vary. We have test-fitted these toppers with multiple expended casings and designed them for a secure fit.

Adhesive may be used if a permanent installation is desired.

Display & Finish

The topper is printed as a single piece and arrives ready for display.

Print colors may vary based on material availability. Slight variations in shade may occur between filament manufacturers.
