Two alleged Lone Wolf bikie gang members have been charged with a string of offences after police raids in Sydney's west.

Police searched a house at St Marys yesterday afternoon at about 1:30pm and charged a 30-year-old man.

Officers say they discovered a shotgun, ammunition, stolen property and various drugs.

The stolen property includes police clothing and badges, as well as over 1000 items of cosmetics.

The 30-year-old was charged with a number of firearms and drug offences as well as dealing with the suspected proceeds of crime.

A 27-year-old man, believed to be part of the Lone Wolf gang, was arrested after police found drugs at his house nearby.

He will face court later this month and the 30-year-old man will appear at Penrith Local Court today.

During the search, police also spoke to a 46-year-old alleged Lone Wolf member about his motorcycle's excessive noise and expired label.
