A Hyannis man is pleading guilty to owning a gas-operated gun.
The U.S. Attorney's Offices say 33-year-old Ryan Diefenbach was in possession of the semi-automatic carbine rifle and was indicted in federal court in 2021 along with co-defendant Donnell Pina, who's case is still pending.
According to the charging documents, "In September 2021, Diefenbach, and allegedly Pina, possessed a Chinese SKS .762 caliber rifle when they sold it to a confidential informant in Hyannis. Due to previous felony convictions, including prior convictions for carrying a firearm without a license, unlawfully possessing a firearm, possessing a firearm with a defaced serial number and assault with a dangerous weapon, Diefenbach was prohibited from possessing firearms."
Diefenbach is facing up to ten years in prison and a fine of up to 250-thousand dollars.
