I don't see any damage either, you may have dodged a bullet.
Go my son and sin no more!
The 95% lower is interesting but we might have a quibble whether it's really that far completed. Nice though that the magwell, receiver extension threads and many other cuts and holes are done. The hardest parts are done, you just need to finish the firing group area.
The biggest issue with assembling an AR isn't so much getting the parts together right - it's getting the right parts together.
