Find more about the custom airsoft gun that people are asking about after they watched the Airsoft GI Hunger Games Airsoft version video... "We got a lot of people asking what gun Bob used during the 1st Hunger Games video, so we decided to do a quick video showcasing what Darren has done to his gun. The great thing is, besides changing the motor and some of the hop-up parts, Darren kept most of the internals parts stock for the past 2 year, and it has worked great for him. Be sure to let us know what guns you would like to take a closer look at, and check out the G4 and FMG4s on our website!"
