Echo1 USA Airsoft sent in news that they have E90 coming soon. This is basically a P90 and the guessing game on what AEG model this is based on has began.

If it's based on the R9, then this fires around 230fps but with a high rate of fire, good enough to become a primary in CQB, which is basically made for. Click on the image below to see more photos.
