It looks like the head cannot be removed from the v2 Archer. If you look at the Youtube video from Selfbuilt, he has to shine a light down the battery tube to look at the emitter electronics. Plus the pictures doesn't show any break lines between the head and battery tube. It would be great if that were the case, the v2 Archer battery tube doesn't look comfortable to use for long periods of time. The V1 Archer battery tube is well built, put simply, Thrunite shouldn't have changed what was not broken.
