Guys I have 6 of these needing to move them. These billets are x-rayed before being milled, have two finger grooves milled in the front of the mag well, and a flared mag well.These lowers are made by SMI inc, and regularly go for $100 an up. These are adonized black, $65 shipped to your ffl. Charlie Sterner has one, he can amen me on the quality of these.
