You don't want the ejector to be flush with the outside of the tube. The weld will be stronger if it is sitting down in the slot. Remember the magazine well will be sliding over this. So the weld needs to be in the slot. If you get any above the slot, you will have to grind it off so it's flush with the tube.. or the magazine well will not go on.
