Can't beat the price!
I've only put a few hundred round through it but so far no jams or anything. Seems to do everything it should.

Overall, the upper is as expected. I gave it 4 stars for functionality, but the very small allen screws used to fasten the free float hand rail rounded out immediately when I tried to adjust hand rail... Poor screw quality lost a star... They'll have to be drilled out, if it ever comes to removing hand rail.
