Opinions os post-ban Colt AR

Since I live in NY I either have to find a preban AR or get something that complies with the ban.

I found this Colt rifle while digging around on the net that seems to comply:

I wanted to see what you guys thought of it.. and to see if anyone has first hand experience with it.

Seeing as it's a post-band compliant rifle I wonder if any of the internal parts are different.. if i should decide to swap out parts later on

What do you guys think? crap? or a good first AR type rifle?
