Another variant of the Model L is found in the United States; as a fully automatic firearm, it cannot be imported as a machinegun for civilian sale. However, if the receivers are cut in compliance with BATFE rules, all the parts may be imported, and the rifle reassembled from a new US receiver. Some are professionally built for the US civilian market; some are home made, with home builders purchasing stamped flats of the receivers and bending and welding the receivers themselves.
