JLS FN2000.

This thing is a BB-hose. I bought it because I liked the shape, and wanted a sci-fi looking prop for Firefly, but the FN2000 is a beast. It'll drain a low cap in under 2 seconds.

Skirmished once, and took it out more often than my G36. Two slight niggles, the monkey metal flash-hider has snapped clean off, and the single shot capability has failed. Niether detract much from the rifle. The battery was the cheap standard supplied one, no problem there, and the mech didn't jam or refuse to feed once.

It also takes M16 mags, though they need some modification if they are not hi-caps.

All in all, i reckon I got pretty good value for my money. This beast cost me less than the PSG1 (which is rubbish).
