PSA AR15 Lower
from what i have heard these are areo made lowers that are slightly rough finished.
the price is $79.99 with free shipping. supposedly you get $15 off by putting the code "ar15.com" don't know if the code is still working or not. would be worth a try cause the $60 blem sale at DS Arms is over.
don't know if the still have the $9.99 pmags --i'll look around!
