Benelli R1&MR1 Charging handles

[Drillbit]

Hey there,

Have an R1 and want a bigger charging handle.

Does anyone know if the MR1 handle or maybe the M4 will work in the R1?

I have a SBE II and it's different.

Thanks!

Anyone cleaning their MR1 and can take a pic of the handle would help.

Anybody?

Tried Emailing Benelli, but they won't talk about any interchangability between any of their products.
Tried looking at pictures & parts diagrams of an MR1 but can't find a good pic.
