Nerf dart tag hyper fire (modified)

An early 2000s nerf gun made for the original “Dart-tag” line, the hyperfire was one of the bestselling of the series. With a 10 round front loading drum, a top bar primer and an incredibly ergonomic handle, it was and still is a favorite among us in the nerf community. It has had 2 internal mods done on it. (1) Air restrictors have been removed. (2) a more powerful spring has been put in. Bought at $10, put in about $10 on mods. Am open to reasonable offers. Not for children under 7 years.
