Did he mine the metal himself?

How strong does the lower have to be? Does it do anything more than hold the buttstock, trigger group and magazine in the right place? Does it it have to be one piece?

Bushmaster makes "Carbon 15" rifles with a plastic receiver . . . that should give an indication of how much stress it's under. I guess as long as the recoil spring & buffer can stand up to the bolt's motion, it's fine.

Sounds like everyone is just assembling parts.

This link is a lot closer to what I consider a "scratchbuilt" AR . . . though he still bought an upper: http://www.geocities.com/elmgrove1765/p ... ject6.html
