New classifications by the ATF have made the Fostck Origin illegal without special permits that allow the ATF to check on you at any time. The new classifications classify the gun as a short-barreled shotgun and a destructive device.
FosTech tried to replace the folding stock with a fixed stock to get around the new regulation, but it did not work. FosTech released a letter to everyone that has purchased the gun with their options.
here is another video of the FosTech origin “firearm” and shotgun. This explains how FosTeh was able to get around the ATF laws originally before the reclassification was made.
