Mesa Tactical has long been a supplier of MIL-STD-1913 (NATO STANAG 4694) Picatinny rails for tactical shotguns. Additional Picatinny rails are also available for the mounting of optics and accessories, such as lights and lasers.

Receiver-mount rails are made to be mounted onto the receivers of Remington, Mossberg, and Benelli shotguns with pre-drilled and tapped mounting holes. These rails can also be used with weapons that are custom drilled and tapped. Mesa Tactical makes Picatinny optics rails for several popular shotgun models that feature pre-drilled and tapped holes in the tops of their receivers.

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.

All Mesa Tactical Picatinny rails are machined from 6061-T6 aircraft quality aluminum, and finished with Mil-spec Type III hard anodizing. Mesa Tactical Picatinny rails include all necessary mounting hardware.
