Video - More home-made steel AR15 lowers

Saw these on YouTube by user bryan fox.  Homemade AR15 lower receivers made of thin sheet metal, unlike The Flat Spot's lower kits which are relatively thick (not that there's anything wrong with that - The Flat Spot's ar15 receivers are nicely made).

The first video shows that one of the receivers was assembled using screws and silver solder, for those who can't weld.  The screws were cut flush with a grinder.

The second video sheds a bit more detail on the construction.  The buffer tower was assembled via wrapped sheet metal around a buffer tube castle nut and presumably soldered or welded in place.  Seems a bit more complex and time-consuming than my proposed steel lower ideas because I think hammer forming sheet metal takes a lot of trial and error and guesswork - however, I do think that this thin sheet metal method does look more refined and less 'chaotic' than my Home Depot lower.

I'd like to try something like this eventually, and when I do I will report my findings.
