Citadel Warthog magazine extension

[Bdolo1967]

Does anyone know what type of magazine extension this shotgun takes? I know this type of shotgun is a Turkish model that is sold under a variety of different names. I have read online that the 870 extension will do, but also seen where the Benelli Super Nova extensions will work. I do understand that there will be minor adjustments made to the current magazine tube.

You can use the mag tub extension that fits benelli nova from carleson. I put it on mine no gunsmithing needed. Exact fit. Changed mine to 7/1.
