A man has been shot in the buttocks outside a home in Sydney's southwest, marking the city's second shooting in as many days.

Police were called to the home on Janus Street, Glenfield, around 10pm on Thursday after reports of multiple gunshots in the area.

The 36-year-old victim was found in the street with a gunshot wound along with several casings on the ground.

He was taken to hospital in a stable condition and will undergo surgery.

The street remained cordoned off on Friday, allowing forensic officers to scour the area for more evidence.

Police are also looking into reports two motorcycles were seen leaving the scene.

The shooting came a day after a suspected bikie gang associate was shot in the head while reversing out of his driveway in Chester Hill.

Radwan Zraika, 39, is recovering in Liverpool Hospital in a stable condition with multiple gunshot wounds.

Police have refused comment on speculation the victim is a Hells Angels associate.

It's not yet known if the incidents are related but a investigators are "looking to see if there are any links," a NSW Police spokesman told AAP.

"If any witness saw anyone on those motorbikes leaving the scene please contact us," he said.
