Mount fits fine and looks good. hardware not perfect. - GG&G Benelli M2 Scope Mount

The screws for my mount were all a fraction too long and extended far enough through the inside of the receiver that I could not install the barrel while the mount was installed. There are two solutions for this situation; you can either loosen the mount every time you remove/install the barrel and then tighten the screws once the barrel is in place, or you can file the screws down incrementally and keep test fitting the barrel until it slides in and out with the mount fully installed. I did the latter after not being satisfied with the former; not a big deal but something to note.

No issues with the fitment of the mount itself though; looks great.
