GRB-39 Practice Projectile / Inert Grenade for K98 Launchers or WWII Nazi GrB39s not applicable for PzB-39 Anti-tank rifle

I am perhaps the leading expert in the USA on the WWII PzB-39 and GrB39 anti-tank rifles. I have several GrB-39s and a PzB39. I also have authenticated most of the GrB39s and PzB 39s that have come to auction in the past 8 years.

I made these projectiles / fake / inert grenades for use with my regular K98 grenade launchers and the GrB 39. They are 6 - 3/8” long and have the exact same profile, rifling and outer diameter of the real K98 grenade. They also have a hole drilled at the bottom that is 0.524” O.D. for tracer compound and a hole (0.575")in the nose to accommodate a 14.5mm spotter tip (ones like you see in a 20 gauge shotgun round).

The rifling mates perfectly with all 7 of my K98 or GrB launchers. Over the years I have tested many different methods / materials / prototypes and these are the only ones that actually work. The rifling is critical and allows you to hit something the size of a car door at 100m all day long.

These are made from billet 7071 T6 aircraft aluminum and thus are re-useable. I have fired these at Knob Creek MG shoot for many years and as long as I can find them and no one hits them with a round they are reusable time and time again. The placing of a spotter tip in the end makes them more entertaining and easier to find as they do not bury themselves on impact. When they hit the ground the spotter tip sends them fling backwards like a whirlybird about 25 feet. The detonation of the spotter tip does not distort the aluminum and usually self ejects the spotter tip.
