Like new Benelli m4 scalarworks sync mount for aimpoint micro type optics. Also fits a lot of other shotguns. I didn’t have this on my Benelli m4 too long before I sold it. It comes with all of the necessary hardware. I will ship on your dime. There is no better way to mount a micro type optic to your shotgun. Can meet in canton. Or cabelas in acworth during work hours. I accept PayPal and cash app
