A convicted felon was arrested in the south Wrigley area of Long Beach for allegedly possessing seven firearms, authorities said Thursday.

William McMurray, 48, was taken into custody Wednesday at his home in the 2000 block of San Francisco Street, according to the federal Bureau of Alcohol, Tobacco, Firearms and Explosives.

“The Los Angeles (ATF) Field Division received intelligence … that a local man was making online purchases of Glock Auto Switches—devices used to convert semiautomatic Glock pistols to machine guns,” according to the ATF.

Authorities served a search warrant at McMurray’s home and seized firearms that included “AK-type 7.62x39mm machine gun, AR-type 5.56mm machine gun, Sten-type 9mm machine gun, Glock-type 9mm machine gun, Glock-type 9mm pistol, Glock-type pistol frame made from a receiver blank and AR-type receiver made from a receiver blank,” according to the agency.

Among the other items seized were various large-capacity magazines, ammunition, a tactical vest and firearm manufacturing materials, the ATF reported.

McMurray was arrested and on suspicion of possession of an assault weapon and being a felon in possession of a firearm. He was released late Wednesday on $35,000 bail, according to sheriff’s department records.

In 2002, McMurray was found guilty of assault with a deadly weapon—a firearm—and was sentenced to eight years in prison and 36 months of supervised release, according to the ATF.

“Based on his conviction McMurray is not permitted under federal or California state law, to buy, possess, or sell a firearm,” the ATF statement said.
