The UCF Police Department said it received anonymous tips that engineering student Max Bennett Chambers, 19, was in possession of an illegally modified weapon that violated state law and university policy.

Officers asked Chambers to search his vehicle outside his dorm at the Towers at Knights Plaza. Inside, investigators found a black AR-15 that had been modified into a fully automatic rifle. Chambers told police he had altered the gun with a kit he purchased online, according to the arrest affidavit.

The AR-15  was test-fired by a certified firearm instructor from the Florida Department of Law Enforcement. During the test, the weapon fired all six .223 caliber rounds in the magazine with one trigger pull. A second 22-round magazine was put into the rifle, and when pressed, it fired 19 rounds in a single trigger pull. The remaining three rounds came out with a second pull. 

"The test fire confirmed the AR-15 is a machine gun," the report said.

Chambers also allegedly manufactured and possessed three drop-in auto sears, which are "a combination of parts designed and intended for use in converting a weapon to shoot automatically more than one shot, without manual reloading, by a single function of the trigger," according to the Bureau of Alcohol Tobacco and Firearms.

Police said Chambers told them he tested one of the drop-in auto sears he made in December 2018 on his AR-15 rifle in early January and successfully fired it as a fully automatic.

Chambers said he knew manufacturing and possessing drop-in auto sears was illegal but said he "does not like laws," the affidavit said.

The Orlando Sentinel reports UCF Police talked to Chambers last year about keeping a part of a firearm in his dorm against school rules but did not arrest him.

UCF prohibits students from carrying guns on their person while on campus, but does allow adults to possess "a lawfully concealed firearm or weapon within a private conveyance so long as the firearm or weapon is securely encased or otherwise not readily accessible for immediate use," according to school policy

Chambers was charged with possession of a machine gun and a bump-fire stock. He is currently being held at the Orange County Jail on $5,150 bond.

UCF Police added that the engineering student has also been trespassed from campus following his arrest, though Chambers expressed "no direct threat to the university community."

"However, his disregard for firearms laws was concerning – and ultimately illegal – especially in this day and age," the department said in a statement.
