Reintroduction of the Pietta made PPS-50. Ruko used to import these into Canada. The design originated with John Farmer of Hard Times Armory in Tennessee. He offered these as select fire conversions, some with integral suppressors, no vents in the barrel jacket. Acton is based on the AR-7, with a separate sear and trigger, not the AR one piece. The drums work better than the box magazines. Forget importing them from the US. It would likely be easier direct from Italy. The magazines would be a problem for export from the US. Ones made for the Cdn. market could have a shorter barrel.
