I say good deals, decent quality. Have several PSA parts, one complete upper, all have run without a hitch.

The upper DID have a slightly canted FSB. Was able to be zeroed and shot just fine, I think it was around 21 clicks left though.

Shaved the FSB and put a VTAC rail and Midwest fixed front site on. Kicks even more ass, now. 5 clicks left, I think.

But that upper, another BCG, some lower parts, RE and buffer, etc......all been fine.
