The Raider/Rampage have one of the longest top rail mount of any Nerf gun. If you looking to add accessories these are the guns to do it. There are two rails included in the set, a 22 MOA back rail and a 22 MOA front rail. However in order to install these rails you must remove the Nerf "Stops) on both side of the font Nerf mount. These Nerf "Stops" prevent the back and front rail from sliding on.
Back Rail Mount – 22 MOA
Front Rail Mount – 22 MOA
These rails are specifically designed to fit on the mounts on a Nerf Raider or Nerf Rampage. However in order to install these rails you must remove the Nerf "Stops" on both side of the front Nerf mount. These Nerf "Stops" prevent the back and front rail from sliding on. See attached picture. These rails will not fit any other application.
These rails are the slip on type. They are 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.
Back and Front Rail = 8.46” (16.48cm) long, 1.0” (2.54cm) wide and 0.75” (1.90cm) in height.
You will need a 3/32” hex wrench to install this item.
