I'm putting up for sale my Fab Defense BM-4 Polymer 4 Rail system for the Benelli M4. I purchased this for my 11707. Apparently this was not made for the 11707, but was created off of the 11703 platform. I haven't been able to get a official word from Fab-Defense as they will not return any of my emails. http://www.fab-defense.com/en/catego...il-system.html
It looks like it can easily be dremeled out to make it work to clear the pistons but i decided to go a alternate route. With it installed as it sits on a 11707 it will have severe cycling issues. It does have some grooves in it, where my pistons have already started to wear a groove on it. http://www.benelliusa.com/forum/showthread.php?t=16813
