This is a draft model of a 40mm grenade in HEDP form for an M79, M203 or MKIV grenade launcher.  It includes a screw on HE “warhead” to complete the container aspect of this.  The imprint in the base is a little weak and shaping of the casing and “warhead” will be improved but for now, pretty happy with the utility of this little item to hide bills and such in plain site.  Print with a gold warhead and green shell casing
