A Cayuga County man was sentenced to prison Friday for having an unregistered and short-barreled AR-15-style rifle, federal prosecutors said.

Investigators were led to Duane Hollenbeck’s camp in Pitcher, Chenango County, after a concerned gun retailer reported Alec Hollenbeck making large purchases of ammunition weekly for more than a month, prosecutors said in a criminal complaint in federal court.
