Gunsmithing Good company for ar15 80% lowers

I milled an 80% .308 lower by Juggernaut. It's only 6061 billet, I hear the 7075 is easier to mill. Took me about 4 hours. Replaced my DPMS Panther lower. When I pull the trigger, the hammer falls and sets off the primer so I guess I did it right! :) desert warrior products dot com
 
If you lived in a place like I do (CA) and had to deal with our firearms laws you would understand. They sell 5.56 and .308 "paper weights" at the local survival store. I don't have any but they are rather popular out here.
