Among the weapons seized were modified Uzis and AK-47s, silencers and hand grenades. An official with the Bureau of Alcohol, Tobacco, Firearms and Explosives said one of the 10 suspects arrested in the raid, Randall Brown, 53, of Godfrey, had set up shop as an illegal gun maker, using kits to turn the Uzis and AK-47s into fully automatic weapons. Some of the weapons were being traded for cocaine, according to the ATF.
