93540 : Picatinny Rail for Mossberg 500 W/Pic Rail Clamp 12Ga 20" rail Black


Top mount rails work with Remington, Mossberg and Benelli shotguns that feature factory tapped rail mounting holes in the top of the receiver. 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.

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.

Mossberg rails attach directly to the receivers of late model (1997 and later) Mossberg pump shotguns with pre-tapped holes. The 20 inch rails are anchored at the front by a magazine clamp that features either a short length of Picatinny accessory rail at the bottom, or a sling swivel stud. The front clamp interferes with the barrel lug on 18 inch Mossberg 590s, and so are incompatible with these platforms. Twenty inch Mossberg 590s fit just fine, however.

The rail will fit on 18 inch Mossberg 500 and 20 inch Mossberg 590, but it will not work on the 18 inch Mossberg 590. The problem with the 18 inch Mossberg 590 is the barrel ring interferes with the clamp.

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 provides two methods for mounting Picatinny rails to tactical shotguns. For Remington shotguns, we offer the Mesa Tactical Saddle Rail, which mounts to both sides of the receiver and wraps around the top.
