Still moving ahead. Just trying to figure out the least amount of fixturing and tooling changes. Not sure if we will use one mill for drilling and one for milling. The 3-axis CNC we will be using does not change its own tools. Does any one have a problem with the trigger hole in the bottom the lower being 3/8" instead of 5/16", it would save one tool change and not affect function of lower. You would never know it was not mil. spec unless you had calipers.
