Benelli M3 Stock Nut

[Josh3239]

I'd like to change the stock on my Benelli M3 and can't seem to find the answer to this question. What size socket do I need to loosen the buttstock nut so I can change stocks?

Big thanks to whomever can answer this for me.

13mm

+1 on the 13mm

I use a standard 1/2" drive socket. For a 1/4" drive socket you will likely need a deep version in 13mm.
