Not quite sure if this is really a TM based-one, but their description says it is so or they reused old TM FAMAS decription for this product. Just enquire at Evike.com to confirm this... "This style AEG is one of the first AEG Tokyo Marui manufactured. This is the older version of the FAMAS series with built-in bipod. It has a very long barrel almost as long as G3 for a good accuracy. The gear box is also one of the highest cycle rate gear box out of all Tokyo Marui AEG models. This is a great gun as well as a great collector's piece because they don't make much of this gun anymore.
