The ERTL Rapid Fire Dart Gun is a toy intended to replicate the look and feel of a real shotgun. It was produced with realistic colors and even features a working safety. Only the front end gives away the fact that it is a toy. It is also a hefty blaster, weighing in at about 4 lbs (~1.8 kg).
In its stock form, it fires large darts a distance of 20-25'. The darts are similar in size to Nerf Megas. The turret rotates on the prime and is exposed enough to load 5 darts at once. As a stock blaster, the RFDG isn't very good; its value comes from its modding potential.
