Introduction and Overview

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.

Recently Mesa Tactical was asked by several law enforcement agencies to produce a Picatinny rail that can be mounted on the right side of the Remington 870 and allow a weapon light to be secured behind the ejection port. This is for door breachers who need more light in tight quarters where lights near the muzzle would be unsuitable. We also offer a rail for the left side of the receiver. These rails are compatible with SureShell carriers mounted on the opposite side of the receiver. As with all our rails, these are machined to the MILSTD 1913 specification from 6061-T6 aluminum, and features a mounting system similar to that of our SureShell aluminum shotshell carriers.

Picatinny Rails

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.

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.
