Haven't mounted one on my Stoeger yet and frankly don't plan to.I had one on my old Remington 870 and the RDS was fine but the mount that went between the receiver and stock was flimsy. I had an aftermarket stock and had to switch back to the original for the mount to fit. Not sure if the mount is similar for Benelli's, but if it goes between the receiver and stock, then I would give the quality of the fit a good hard look. My mount never sat where it was supposed to and I couldn't get it to conform to the stock as it should have. It may have been a manufacturing defect, who knows. Just saying don't frustrate yourself trying to fix it if you run into my same issue. But other than myself, I've never heard anything bad about the SpeedBead. It's a good red dot sight to boot, but the mount (for me) was not a quality product. Hope this helps!
