great instructions (need better camera stand), without this I would not have figured out how to put my new M4 together as the factory manual is completely missing the first few steps.
Really need a better quality video and also was the camera person asleep as he was missing all the key camera angles when the instructions was given. He needs to point the camera at the key areas, not at the instructor.
anything made in China is just junk. Not only are you buying junk, you are helping the Chinese steal American Jobs.
