BOSTON — A Massachusetts man who illegally possessed assault-style weapons and ammunition has been sentenced to seven years in federal prison.

Thirty-six-year-old Robert Kurtzer was sentenced Thursday by a federal judge in Boston to serve seven years in prison with three years of supervised release. The Patriot Ledger reports ( ) that Kurtzer plead guilty in April to possession of assault-style firearms, which he had been banned from owning due to a prior conviction.

Kurtzer was arrested in 2016 after he told police — who had stopped him for a traffic violation — that he had a large number of weapons in his vehicle. In a later search of his home in Weymouth, police found two AR15-style assault rifles.
