The lack of plastic "Sub-Ammo" sleeves has sidelined those SMG guns for decades, the guns first appeared in the late sixties and had about a decade or so of use before they became orphans.

If someone wants to get these guns back into action the best approach would be to find that tooling and have more sleeves manufactured. Failing that you need one for a sample to replicate, they do exist, but are held for "museum" purposes.

Finding parts for the Johnson SMG speargun is a challenge due to the fact that they are no longer manufactured and haven't been for quite some time. These spearguns use “.22 caliber blank cartridges” to propel the spear, which is a unique design compared to most modern spearguns.
