I finally got around to doing a bit of machining on the AR15 forgings I had acquired. Got the outside contour milled and the numerous holes and slots cut for the safety, mag release and hammer pivot, etc. It's been a while since I've machined any 7075 and I must admit, the stuff is pretty impressive. Nice sharp end mills are a must.
