There was a thread quite a few months ago with lots of negatives how this guy does business. One of our members really got wrung through the nutcracker. I think each gun stands alone, some good, some terrible. It just depends on the parts he used at the time and his state of mind at the time.
Can't tell much from that picture...
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
