Machining an AR15 lower receiver

[d65]

Very impressive ! I wish I had your machining skills! I just finished an 80% AR Lower in cast aluminum and I thought I did a good job. In my defense, this was my first project on my new cheapo Grizzly mini mill. Never have used a mill or lathe before. You however, look like you may have been at this awhile!!! I love the learning curve.
