Can a supernova 20160 be used for duck hunting?

[Msatlant]

Ordered my first shotgun from a third party website and didn’t realize I picked the tactical model. 
can this be used for duck hunting as is? Or should I look to get a replacement barrel/totally new shotgun?

From a legality standpoint that model can be used for duck hunting (as long as the magazine is plugged so the gun hold no more than 3 shells total).

From a performance standpoint the GR sights, short barrel and lack of choke constriction will severely limit its usability for what most hunters consider an ideal duck gun.
