Michael on August 25, 2019 I bought this for a Benelli M4 (the "LE" version with the collapsible stock) and out of the box it appeared it would not fit. The threads on the screws seemed JUST (ever so slightly) too big for the stock’s sling area. I tried working the hole bigger by jamming in some stuff and working side-to-side and I also contemplated adjusting the stock sling-hole area to better accommodate the sling mount (via actual drilling) but after finding both of my drill batteries dead I tried to strong-arm the screws through by hand. As fate would have it, I was able to get the screws through the Benelli stock (almost “threading” through the stock’s sling opening) and now have the back QD sling mount in place! I’d recommend for anyone trying to do the same, do your best to leave the stock stock (see the pun there?) intact and fit these parts into it as best as possible. I was afraid I might deform the screw threads but I was able to get it installed and holding firm as delivered. I should probably give it 4 stars but it's in place and I didn't need to do any drilling/filing so 5-stars it is!
