Yea you do live in a mucked up state . I to used a AR15 10.5" upper with bcg from psa for the AR9 to ar15 change over. When I was reading and asking for advise on my first ar15 builds I was asked if I wanted to use the tools needed from forum member that lived about 40 minutes away , I did for my first build . You might have some one close to you on a forum that has the tools needed to assemble a future AR too. I ended up buying the couple items I needed from ,, darned if I remember now . But today amazon and psa can more than likely save you a few bucks if you decide to assemble your own or upgrade in the future .
Like I said for now the PSA 10.5 556pistol upper has been running fine . Our AR15 carbines to use criterion hybrid chrome lined barrels and tool craft bcg , hyperfire triggers so cost could have been reduced by using other parts but ours sure are shooters .
