The Brain Exploder posts a video on his second go with the American Airsoft Factory M4... "Full blowback airsoft replica, a gas blowback killer, perfect training weapon... so they said. On this second go round with the AAF (American Airsoft Factory) M4 I put it to a field test and the results are a rollercoaster ride that ends in a death metal medley. 

To get a better idea of why this gun is even worth the time check out the introductory video from a few months ago... Much has changed for the better but we are far from perfection. The good news is I am in constant communication with the makers of this platform and they already have an improved version so we are slowly getting closer to something that might be a winner."
