For sale is an airsoft P90 AEG - I don't remember the brand name, but I think it may be a Kart P90 TR. It's been years since I last played airsoft and I've grown out of it, but this was my favorite airsoft gun - it's really practical and a no-nonsense design. It's a good one, whatever brand it may be (I seem to recall it was a Tokyo Marui knockoff). The body is made of ABS plastic, but the upper receiver and rail is all steel. It also still works, as I just charged up one of the batteries and tested fired it.
It comes with a variety of extras: a case for carrying the airsoft gun, some bb's, a speed loader, a couple red dot sights, four mid-cap magazines (they hold up to 150 bb's iirc), some batteries/chargers, a mouth/nose mask, a camo jacket and vest with pouches for carrying P90 magazines, and a pair of goggles with a built-in defogging fan. You've gotta wear your eye protection when playing with airsoft guns, but it sucks when it fogs up while running around, so the little fan is a huge help
