I built several on Nodaks but for the past couple of years I have used Childers exclusively. Great receivers, nice people to do business with, and you can them with selector stops or without, engraved with various country’s markings, trigger humps, drilled for trunnions, not drilled, and custom serial numbers. They are more than a Nodak, but IMO, worth it. Currently about a 10 week wait, though.
