SureFire's MR11 Weaponlight adapter allows for the installation of a SureFire light on the rail-less Berretta models 92, M9 and 96. The lightweight, low-profile design enables the MR11 to fit into most holsters made for the Berretta 92. The unique design of the MR11 allows it to be installed with the rim of a cartridge instead of a hex wrench.
