Top Mount Picatinny Rails
Mesa Tactical makes Picatinny optics rails for several popular shotgun models that feature pre-drilled and tapped holes in the tops of their receivers. Top rails for the Remington 870 use the tactical hole pattern introduced on some tactical 870 models in the summer
of 2007. Mossberg rails attach directly to the receivers of late-model (1997 and later) Mossberg pump shotguns with pre-tapped holes. Standard profile Mossberg rails are for general purpose optics mounting applications. Tall profile rails are only for use with Mesa Tactical High-tube telescoping stock adapters, as an alternative to adapter mount rails. Receiver mount rails allow easy access to the Mossberg safety switch. The hardware included with the Remington and Mossberg rails are for pump action shotguns. They can be used with semi-auto versions (Remington 1100 and Remington 11-87, or Mossberg 930) by grinding the fasteners down to the appropriate lengths. Rails for the Benelli M2 Tactical and Benelli SuperNova Tactical mount just forward of the ghost ring sights, extending to the front of the receiver. Benelli M2 Tactical rails can also be installed on round-top Benelli M1 receivers after drilling and tapping the top of the shotgun receiver with #8-40 threads. Consult a gunsmith.
The Picatinny optics rail for the Kel-Tec KSG features small aluminum flanges on either side of the main rail can accept additional lengths of Picatinny rail to support weapon lights or targeting lasers (rail not included). A pair of unique steel recoil blocks featuring angled set screws ensure the rail assembly is securely mounted to the shotgun.
