I haven'd done it on an Archangel stock, but if you inlet just the ridge area, it will not cause the receiver to set any lower in the Archangel than in any other stock. The only Archangel I have had, I received with a rifle built on an Armscorp receiver. I sold the stock with a SAI rifle in it. It had material removed from the trigger pad areas from a previous owner and both locked up tight. From what I understand the stocks are made so that most of the time material must be removed to achieve trigger group lock-up, so you should be fine.
