Police also collected 89 gun parts, 19 imitation guns, 10 home-made or 3D-printed guns and 130 home-made or 3D-printed gun parts.
The home-made firearms were a major focus of the operation, and were involved in some of the biggest busts.
Just before 7am on Monday, October 13, police carried out a search warrant in Hinchinbrook, Sydney, where they allegedly found a 3D printer attempting to print a gun part.

A 52-year-old man was arrested and charged with 14 gun-related offences.
Detective Superintendent John Watson said criminals were innovating, but so were police.
"Privately manufactured firearms present a fast-evolving challenge, but this operation shows what's possible when agencies collaborate effectively," he said.
"These 3D printed components may look colourful, but they are not toys. Once assembled, they become lethal weapons – entirely illicit and extremely dangerous. That's why we're targeting the full supply chain, from printers to imported parts.
"These practices are unsafe, unlawful, and they erode the integrity of our licensing framework; we will continue to act decisively to stop them."
