Mesa Tactical is an important pioneer in the provision of MIL-STD-1913 Picatinny rails for tactical shotguns. A Picatinny rail for the mounting of sighting optics is included with every Mesa Tactical High-tube Telescoping stock adapter kit. 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 Mossberg shotguns pre-drilled and tapped for sights. These rails can also be used with weapons that are custom drilled and tapped. 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.
Receiver mount Picatinny rails
Mesa Tactical offers two methods for mounting Picatinny rails to tactical shotguns. For Remington 870, Remington 100 and Remington 11-87 shotguns, we offer the Mesa Tactical Saddle Rail, which mounts to both side of the receiver and wraps around the top. Top mount rails work with Mossberg 500 and Mossberg 590 shotguns that feature factory tapped rail mounting holes in the top of the receiver
Remington saddle rails
Mesa Tactical Saddle Rails comprise 6061-T6 aluminum brackets that wrap around the top of the shotgun receiver. The factory trigger pins are replaced by internally thread steel pins, to which both sides of the saddle rail is securely bolted. The saddle rail is Type III anodized for a rugged surface finish. We also offer a version of the Remington Saddle Rail that includes a SureShell shot shell carrier. (See SureShell carrier section for more details)
Our Saddle Rail is specially contoured to allow operation of a semi-automatic bolt on the right side of the receiver, so it can be installed on Remington 1100 and Remington 11-87 semi-auto shotguns as well as Remington 870 pump shotguns.
No fitting or gunsmithing is required to install.
Mossberg rails attach directly to the receivers of late-model (1997 and later) Mossberg shotguns with pre-tapped holes. These rails can only be fitted to later-model Mossbergs featuring factory tapped holes in the receiver.
Standard profile rails are for general purpose optics mounting applications. These rails adhere to the minimum height requirement of the MIL-STD-1913 specification, and should not be used for mounting optics with the High-tube telescoping stock adapters.
These rails can be installed on other shotguns by tapping the top of the shotgun receiver with #8-40 UNS threads. Consult a gunsmith.
Adapter Mount Picatinny Rails
Adapter Mount Picatinny Rails fasten to the accessory mount points on the sides of Mesa Tactical High-tube and Low-tube telescoping stock adapters, not on the shotgun receiver. The can also be used with our new barrel and magazine clamps, which feature the same mounting hole patters as our stock adapters.
Standard profile rails like the Stubby adhere to the minimum height requirement of the MIL-STD-1913 specification, and should not be used for mounting optics with the High-tube telescoping stock adapters.
Tall profile rails are designed to mount optics for use with High-tube telescoping stock adapters, or to mount accessories slightly away from the receiver when fastened to the telescoping stock adapter side accessory mount points. When used for optics, the elevation of the tall profile rails is similar to that of a flat top AR-15.
Adapter Mount Saddle Rails
Our adapter mount saddle rails are secured to both sides of a telescoping stock adapter, cantilevering forward over the receiver. They provide a convenient means of attaching a Picatinny sight rail to shotguns equipped with our Low-tube telescoping stock adapters; or, for High-tube adapter shotguns, an alternative to the sight rail screwed into the top of the adapter. No alterations to the shotgun receiver are required.
The rails can be fitted onto Remington 870s with Low-tube adapters and Wilson Combat ghost ring sights, allowing the iron sights to act as back-up for a scope.
