Look up the antipersonel version of EFPs. My Walmart is out of claymores but you can improvise if you want to risk going to jail.
However, a homemade carronade being muzzle loading and not a bomb IS legal in most places and having an electrical firing system is still legal. Ill leave the rest to you imagination. Hint when the Victory first fired on the Bucenture Nelson used carronades which caused huge casualties on the French ship.
I actually posted this as a joke.
I don’t need to buy claymores
