All of these shells have been fired from a Bradley TANK, AC-130 Gunship, F-35 Lightning II or MK 38 Auto cannon (mounted on a battleship). The tips look like the real deal, but are machined aluminum. This opener is huge, measuring 8" tall and opens bottles with ease. A great gift or conversation piece that WORKS as well as it looks. All of our shells are battle fresh and have the scratches and dents associated with firing and collecting the shells.
