Just built one from psa and I managed to get great pricing and a stainless 18 inch 7 twist wylde 223 upper with all the pieces was 399 down from 749. Then the lower complete with trigger job for 219. Add shipping and ffl and I am just under 700.
So yeah the mp sport at that same level is a good buy
mjb, I agree. Just don't "need" another AR.
