Actually your groups could get their hands on Gatling Guns and the plans for Gatling Guns fairly easily.
The plans for the original Gatling Gun are available from historical archives and given the fact that it is a civil war era weapon it is rather easy to build one in any modern machine shop.

Here is the 22 caliber version.
It's a tiny thing scroll down to the pictures of a man cranking it.
Since it's hand cranked it's has a very low rate of fire only 700 to 1000 rounds per minute.

Given the plans and a little scaling it would be as easy to build a gatling gun using pistol barrels instead of short .22 rifle barrels shown above.
Even the "toy" .22 caliber version would have it's uses in fiction.
Example
In the Superman Unbound universe the Chinese and Russian Mecha/power armour use tiny .22 caliber gatlings designed around smoothbore pistol barrels as a point defense system to stop anti-tank rockets and anti-tank grenades fired or thrown by American Ultramen.
