Knockbreda got the better of Dundela by the odd goal in seven in a high scoring Lough 41 Championship encounter at Wilgar Park.
The visitors needed just 20 seconds to open the scoring courtesy of a Lee McGreevy header, a lead 'Breda capitalised on with further goals coming through Ethan Devine on 23 and 35 minutes respectively.
The Duns hit back a couple of minutes after going three down via an Owain Beggs spot-kick before David McMaster bagged a second just before the break.
Cillin Gilmour restored Knockbreda's two goal cushion with the second penalty of the game on 53 minutes but Michael Smith brought the Duns back into it once again just after the hour.
However, Colin McIlwrath's side held on to secure the points and their first win of the campaign.
