thats hard to say . at one time we were going on about how cheap we could build an ar-15/m clone.
today thats all out the window. the surplus parts are gone, the glut of ar-15 parts is mostly gone .
considering the panic buying and the gouging going on recently i think it is going to be a long time --obamma is going have to be out of office and a gun friendly administration be in power before we see discount pricing on ar-15 stuff.
there were some pretty decent ar-15s going for $899 not counting mags so $900 for an ar-15 build ain't far off i don't think.
