Drug squad detectives who seized drugs and firearms in raids in Blacktown, Seven Hills and Wentworthville on Tuesday, have seized four more weapons.
They found three more handguns in a Wentworthville storage facility and one sniper rifle in Blacktown.
Strike Force Gurton, set up to investigate the manufacture and supply of drugs, was largely responsible for the raids, which found ice, ecstasy and drugs used in the manufacture of both.
Two men, 32 and 42, both from Blacktown have been charged with the manufacture of illegal drugs and are before the courts.
Strike Force Gurton’s investigation is continuing.
