The Nerf Retaliator's Barrel extension has rail on both the top and bottom. This slip-on rail is for the bottom mount. This rail follows the military specifications and will allow you to mount any Picatinny accessories.
This rail is specifically designed to fit on the bottom mount of the Nerf Retaliator's Barrel extension. There is a recess on the underside of the rail so it specifically sides over the Nerf Retaliator's Barrel extension's mount. This rail can be used on other Nerf guns as well.
This rail slips one the Nerf mount from the front of the gun. It is easy to install, by simply tightening two 10-32 stainless steel set screws which are threaded into the body of the mount. There are additional 10-32 threads in the body of the mount if you want to add oddly mounted accessories.
