An alleged gunman is behind bars on remand after police claim he fired a shot into a brick wall following an argument with a mystery man on the Central Coast.

Paul John Stuart, 56, did not apply for bail in Parramatta Local Court on Monday, having been arrested the previous evening over an incident in Gosford.

NSW Police said officers attached to the Brisbane Water Police District were called to a unit on Gertrude St about 6.30pm on Sunday, following reports of a gunshot.

Officers set up a perimeter before entering the unit and arresting Stuart about an hour-and-a-half later.

Police will allege Stuart had an argument with an unknown man before a gunshot was fired, hitting a brick wall.
