Police say a battle between the Blacktown faction and its Bankstown sister chapter is responsible for shootings that have erupted across Sydney over the last four months.
Mumtaz Qaumi, of Wyong, has been charged with two counts of unauthorised possession of a pistol, one count of unauthorised possession of a shortened pump-action shotgun, three drug supply charges and one count of knowingly directing the criminal activities of a group.
His elder brother faces the same charges and an additional pistol possession charge.
The accusations date from November until last week, but do not appear to relate to the New Year's Day shooting-up of a cruiser in the Rose Bay suburb of Sydney, in which Farhad Qaumi was reportedly injured.
Both men are due to appear before Sydney's Central Local Court on March 7.
A third alleged Brothers for Life gang member who faced court in Sydney will remain behind bars on firearms and drugs charges.
Masieh Amiri, 27, appeared before Parramatta Local Court where his lawyer, Dean Lenz, didn't apply for bail on his client's behalf.
He is charged with attempting to possess an unauthorised pistol and firearm, two counts of supplying a large commercial quantity of prohibited drugs, one count of supplying an indictable quantity of prohibited drugs, and participating in a criminal group, police say.
Magistrate Georgia Knight adjourned Amiri's matter to March 6 at Sydney Central Local Court.
She also scheduled a bail application for Amiri at the same court on January 16.
