I know there is a fair amount of info on chokes for these guns, and I've done a fair amount of looking and have narrowed it down to the choke I'd like to try in it, but the problem is making sure I order the right one. Things I have read say that these have the Benelli Mobil choke system. My question is will a choke for a sbe2 and m2 interchange with the affinity? Only reason I put it like that is I can't find anywhere where it says for Benelli Mobil choke system. It either say for use in sbe2/m2 or benelli/beretta. This is the very only thing that I found about this gun I don't like, other than that I love it.
