The nice thing about the Blackout is all you have to do is replace the barrel and you are good to go. I like it since all you have to do is cut down the brass and form it up, not hard. I am going to get one and start working up some loads. So far the things that I have read about it look real good. My son and I are going to be building AR this summer when he comes home from college. It is a good father/son project............ mom doesn't have to know. I'm off on a tangent sorry.........saw something shiny.......... Thanks for the tip on the magazine I will be picking one up tomorrow.
