Getting ready to order a tube from Rob Roberts for my M2 with a 28 inch barrel. My question is should I get a 660 like I have for my Benelli performance shop sbe2 with a 28 inch barrel?
I would try your .660 first. Rob's chokes are a bargain since you can swap constrictions.
Yeah the .660 would be great
I'd buy a IC 665 especially if your gone with LB's
