At the heart of this pump shotgun is a lightweight steel skeleton framework over-moulded with a high-tech polymer, making the SuperNova Tactical super-light, super-strong and almost completely impervious to any weather condition. Dual-action bars and a two-lug rotary bolt head that locks up steel to steel inside the barrel to ensure that the SuperNova Tactical is rock solid to the core and capable of handling everything from light loads to 3-1/2-inch Magnums.
