I found out that my POF is actually made of 7075, not 6061. I asked a couple of knowledgeable people in the industry and was told that the main reason someone would use 7075 over 6061 is so it can be called "milspec" since that's what Colt uses.
I am going to get QD to make me a lower out of 2024 for kicks and grins.
I also bought a barrel from Green Mountain. I am waiting on a reamer so I can chamber it. I might build me a Plumb crazy lower rifle too, just so I can say I have a plastic gun!
