I wanted to build one.
Then looked at parts, and the few tools needed.
Then the few more to do it right.
Then looked at PSA complete uppers/lowers.
It became obvious real quick that building cheap AR's was the
same game as reloading cheap blasting ammo. (Remember then)
And also that,
with careful shopping,
a high quality gun could be built
relatively cheaply.
Just like loading high quality ammo.
