Mag/Barrel Clamp Benelli Nova

[SharpSig226]

Barrel/Magazine extension Clamp?
I did a research, but can't find any clear answer:
Which model # clamp fits Benelli Nova ?

Been looking for one too. Apparently the nordic comp +2 mag extension is fine without a barrel clamp, but I want the fore-end to be rock solid, and I wanted to mount a rail up there for a small light. In my research I ran across this:

"I have a benelli supernova tactical with pistol grip and a nordic components magazine extension. This clamp fit perfectly with no modifications needed."

Would this work. It was what I was planning on getting for my NOVA. Or do you just want the clamp?

I'm looking just a clamp, company that sell clamps doesn't provide
any information on diameter that can attach to barrel and tube end.
