PORTLAND, OR — A West Linn, Oregon man has been charged with illegally possessing machine guns, unregistered short-barreled rifles, and firearm silencers.
Lucas Christopher Perillo, 41, has been charged by criminal complaint with unlawful possession of a machinegun and unlawful possession of an unregistered short-barreled rifle or silencer.
According to court documents, on June 17, 2025, FBI agents executed federal search warrants on Perillo, his residence, and his vehicle. Agents located and seized 36 firearms, including three firearms converted with machine gun switches and 13 unregistered short-barreled rifles, firearm silencers, and other firearm parts.
Machine gun conversion devices, sometimes referred to as switches, are small attachments used to convert firearms from semi-automatic to fully-automatic.
On July 11, 2025, Perillo was arrested in West Linn. He made his first appearance in federal court today before a U.S. Magistrate Judge and was ordered detained pending further court proceedings.
This case was investigated by the FBI with assistance from the Oregon State Police. It is being prosecuted by Parakram Singh, Assistant U.S. Attorney for the District of Oregon.
A criminal complaint is only an accusation of a crime, and a defendant is presumed innocent unless and until proven guilty.
