MESA SURSHL AL/RMR MNT BEN M4 6 12GA

The line of SureShell shotshell carriers with integrated Trijicon RMR reflex sight mounts for the Benelli M2/M4 and Beretta 1301 shotguns, are similar to Mesa's SureShell carriers with integrated optics rail for those platforms, instead of a Picatinny rail these carriers feature a precision machined mount for an RMR reflex sight (NOT INCLUDED). When installed on the shotgun, the RMR sight co-witnesses with factory ghost ring sights.
