I have one small chamfer up by the charging handle to do, and one small hole to drill and tap in the threaded portion of the buffer opening. Then, just the bluing and engraving.
I used the extra long end mill to finish pocket. I got the mag well where a magazine would slip in, but the 9mm mag adapter would not slip in. had to file it until it would slip in. Made sure 9mm mag slips in and out with ease as well. This one will stay a dedicated 9mm lower. I want to map the opening and make another lower with the 9mm mag opening in it, without having to use adapter. I have extra blank forgings. They are only $20 a pop at the machine gun shoot. I picked up some upper blanks as well, thought they look a bit more tricky on the machining. I am going to try and do at least one upper. Would like to do a whole upper, lower and trigger assembly from metal stock just to have a gun I made from scratch.
