M2 Choke Full Choke diameter (factory)

[EKavanagh]

Does anyone know the diameter/constriction of the factory full coke in the 20ga Benelli M2?

I tried searching online but no luck.

Thanks.

I'm fairly sure it's .590. I can measure one tonite

For factory chokes, you might want to check with calipers. But it should be 595 for Full

Great. Thanks guys. Just got it and will be figuring out choke selection over the winter.

Glades is right, I just checked mine and it's .595 for the full choke.
