Mesa Tactical has long been a supplier of MIL-STD-1913 (NATO STANAG 4694) Picatinny rails for tactical shotguns. A Picatinny rail for mounting optics or sights is included with every Mesa Tactical High-tube Telescoping Stock Adapter Kit. Additional Picatinny rails are also available for mounting optics and accessories, such as lights and lasers.
All Mesa Tactical Picatinny rails adhere to the MIL-STD 1913 specification for firearm accessory rails. It is machined from 6061-T6 aluminum alloy, then bead blasted and Type III hard anodized for a rugged, flat black finish. Mesa Tactical Picatinny rails include all necessary mounting hardware.
The Picatinny optics rail for the Kel-Tec KSG features small aluminum flanges on either side of the main rail that can accept additional lengths of Picatinny rail to support weapon lights or targeting lasers (accessory rail not included). A pair of unique steel recoil blocks featuring angled set screws ensure the rail assembly is securely mounted to the shotgun.Top Mount Picatinny Rail (Receiver)
Top mount rails work with Remington, Mossberg, Benelli and KSG shotguns that feature factory tapped rail mounting holes in the top of the receiver.
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.
Mesa Tactical Saddle Rails are 6061-T6 aluminum brackets that wrap around the top of the shotgun receiver. The factory trigger pins are replaced by an internally threaded steel pin (in the rear) and paired Chicago screws (up front), to which both sides of the saddle rail are securely bolted.
Picatinny rail that can be mounted on the right or left side of the Remington 870 and allow a weapon light to be secured behind the ejection port.
Adapter Mount Picatinny Rails fasten to the accessory mount points on the sides of Mesa Tactical High-tube telescoping stock adapters, not on the shotgun receiver.
They can also be used on the sides of our Barrel Clamps, Magazine Clamps and clamps used as front mount points for 20 inch and 24 inch rails, which feature the same mounting hole pattern as our stock adapters; or our Picatinny rails for the Kel-Tec KSG shotgun.
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 AR stock adapters.
Tall profile rails are designed to mount optics for use with High-tube AR Stock Adapters, or to mount accessories slightly away from the receiver when fastened to the AR 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.
Remove the set screws, if any, from the tapped holes in the top of the shotgun receiver. Store these in a safe place.
Place rail on shotguns receiver so that the holes in the rail line up with the tapped holed in the receiver. Loosely fit the included scres into the holes.
Using the hex or Torx key (included), tighten the screws from the rear of the receiver, moving forward.
It is recommended that you pre-fit the rail to your gun and accessories to the rail before torquing the screws.
Once you are satisfed that everything fits, reassemble the rail to the gun. Torque to 30 inch-pounds (for Remington and Mossberg shotguns) or 18 in-pounds (for Benelli shotguns) and apply a drop of blue Loctite® to each screw before reassembly.
