You could save yourself a LOT of money by printing an ARMP5 V2 or Leber lower instead of buying a Lee Sporting

If you don't clearance the ejector lever, the bolt either won't be able to go fully to the rear or the whole gun will get locked up. Also don't use MAF ejectors, too soft and the cut on them is not to the spec required for the ARMP5 V2. Alternatively, the V0.13 doesn't require a cut ejector, but has worse …
