So does the new Tokyo Marui PS90HC perform? Nothing conclusive yet, but this video testing their latest High Cycle custom AEG shows it averaging at almost 25 rounds per second and an average of 274-277fps in muzzle velocity. If you think that's no big deal, then let's see what happens if a continuous stream of 25bps at that velocity consistently hits you. You'll be really annoyed and sore.

Thanks to Nishiyan240 for the video.
