Mesa Tactical has long been a supplier of MIL-STD-1913 (NATO STANAG 4694) Picatinny rails for tactical shotguns. Adapter Mount Picatinny Rails fasten to the mounting points on top of the Mesa Tactical High-tube telescoping stock adapters, not on the shotgun receiver. Additional Picatinny rails are also available for mounting optics and accessories, such as lights and lasers.

The 9 ½ inch rail attaches to both the High-tube stock adapter and directly to drilled and tapped receivers for a completely rigid mount for optics and accessories.  The combination of the rail and cheek weld height is perfect for the use of AR configured optics such as holographic sights and similar height optic systems. The receiver length rail and the strength of its attachment system is perfect for tactical and personal defense applications. 

Mesa Tactical’s High-tube and LEO telescoping stock adapters allow the use of AR-15 buttstock and grip components to provide collapsing stocks for pump shotguns.  The High-tube adapters feature an elevated stock height for optimal cheek weld with AR height rail-mounted optics, allowing the use of many effective and popular sights on pump action shotguns.

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 receiver length rails are available today, separately or as part of complete telescoping stock kits.
