AIM now has some superior lowers for $89 and aero for $119.
it looks like the supply side has caught up with demand for lowers.
the days of the $79 mega machine are not back yet. but prices are close to normal retail.
the last time a saw a superior at AIM they were $79 and .01 shipping IIRC and the AERO was $99. that was at least a year back.
now if you can find a barrel,LPK and boltcarrier & bolt without getting taken to the cleaners??--the rest of the stuff is out there for not much more than they cost pre-obama.
