A 63-year-old Grandview man, who is also a registered sex offender, is charged with illegally distributing explosive devices.
Robert A. Vik allegedly sold 15 improvised explosive devices in October to an undercover agent with the Bureau of Alcohol, Tobacco, Firearms and Explosives.
He had 27 other devices when he was arrested on Wednesday after arranging another sale with the agent, according to allegations in court documents.
Each of the explosives was described as a fused six-inch long cardboard tube containing explosive powder.
Vik is not licensed to sell the devices and is also a convicted felon who cannot legally possess explosives, according to court documents.
He was charged Thursday in U.S. District Court in Kansas City with one felony count of distribution of explosive materials without a license.
The charge carries a sentence of up to 10 years in prison.
Vik has a criminal record dating to 1976, and is listed on the Missouri sex offender registry for transporting a minor across state lines for prostitution.
