One poster brought up the possible problem with suppliers that plagued Mr. Lamboy from day one. The result was that, years later, we don't know which variation, good or bad, we own or are contemplating buying. It looks like the only part that the Lefever project could face trouble with is the barrel assembly. If the suppliers of the barrel assemblies is reliable, the rest should fall into place. I don't believe Mr. Lamboy had the receiver situation under control before he addressed step two. It would be hard to believe that the barrel suppliers sunk the ship single handed and, as I remember, that did not happen. However, it could happen in the Lefever project if care is not taken.
