Latest video from Airsoft Taiwan shows the new SAT Stainless Steel Inner Barrel for the Tokyo Marui M4A1 MWS Gas Blowback Rifle. A comparison is done showing that the SAT verion is longer than the original inner barrel. A longer barrel can also help improve performance, increasing FPS, range and accuracy.
