Teens busted after 'uploading gun videos'

A pair of Sydney teenagers who allegedly posted several online videos of themselves shooting a gun have been arrested.

Police swooped on the males, aged 15 and 18, at a home in Revesby on Wednesday after they began investigating the videos, which were posted on a social media website.

It's alleged officers found several unauthorised rifles, including a .308 calibre rifle, a rifle scope, a rifle stand, ammunition, and a netball with bullet holes in the home.

The teens were arrested and charged with several firearms offences, with the older boy due to face Bankstown Local Court on Thursday while the younger boy is due in court next month.
