Made for Remington 870 shotguns only, the Medusa Tri-Rail is a one-piece, solid-steel frame with three removable Picatinny rails and a replacement rail that features a swivel sling loop.
In lieu of a rail, the rubber-coated sling loop can be mounted on the bottom, right or left for use with a dual-point sling. One rail is positioned on the bottom, facing downward under the barrel, and the other two Picatinny rails face outward from the sides of the shotgun just above the fore-end.
The Tri-Rail is locked in solidly by the shotgun’s magazine tube cap or magazine tube to provide a secure platform for lights, lasers and other accessories. No tools are needed for installation. Price: $85.
