Outraged bikies threatened police as they seized more than 100 weapons across Victoria today.
The weapons were seized from more than 30 properties as part of a blitz on breaches of firearm licensing laws.
During the raids police also found a pen gun and starter pistol.
Assistant Commissioner Stephen Fontana said long-arm weapons and revolvers were part of the arsenal uncovered by police.
Many of the guns are legally registered but police argue that those who registered the weapons are not fit and proper persons as they are patched members of bikie gangs.
"I have no doubt that some of these seizures will be challenged," Assistant Commissioner Fontana said.
Detectives from the Echo Taskforce were involved in today's operation. "We don't believe that it is right that a club, for instance, the Hells Angels, can get ready access to 38 registered firearms. This is simply intolerable,'' he said.
The seizures took place in St Arnaud, Wangaratta, Myrtleford, Hadfield, North Ballarat, Kyneton, Wodonga (various suburbs), Traralgon, Melton South, Yarragon, Cockatoo, St Andrews, Lalor, Mill Park, Benalla, Baddaginnie, Tallarook, Belmont, Werribee, Hoppers Crossing, Doveton, St Kilda, Bunyip, Coburg, Tullamarine, Springhurst, Pennyroyal, Officer and Kilsyth.
Almost a year ago Victoria Police revealed that they had seized more than 50 weapons and drugs and cash during more than 52 raids on properties linked to outlawed motorcycle gangs since February.
Police expect to lay charges as a result of today's operation.
