Correct, and the recoilless black powder launch cartridge is a thing of simplicity and reliability. We also found that the circa 1943 shaped charge warhead remains remarkably effective to this day, and an improvised Panzerfaust 60 can penetrate 12-14 inches of face-hardened armor plate today, just as it did then.
About $40 to build the launcher, three to four times that for the projectile, depending on your economies of scale.
