3D Printed 40mm brass topper

** This is a printed prop, non-functioning, and for display purposes only **

This is a 3D printed replica of the 40mm HEI round used by the AC-130. Intended for use on top of expended brass for display only. Each is 3D printed as one piece. Brass not included. Complete your brass collection by topping it with one of these and showing everyone what a complete round looks like.

Due to heat expansion during firing the fit may vary slightly between different pieces of brass. But we have tested these on many pieces of brass and they fit universally. For a more secure fit recommend gluing the topper in place.

Printed in PLA. Each one is about 164mm tall and weighs 48g.

Product is made to order.
