BOSTON — The man described by authorities as the regional leader of the Outlaws Motorcycle Club has been sentenced to more than two years in prison for being in possession of an unregistered gun.

Federal prosecutors say 48-year-old Bruce “Monster” Sartwell was sentenced Wednesday to two years and three months behind bars and three years of probation.

Federal authorities in October 2019 intercepted a package from China addressed to Sartwell that was labeled as a “fuel filter” but which actually contained a firearms silencer.

Authorities say a search of his East Bridgewater home led to the discovery of an unregistered AR-15-style gun as well as gun manufacturing tools and ammunition.
