I have made a couple for others. I just make them to order. It depends on how many parts you already have. Many converted M2's still have the original hammer, and sometimes the sear, which helps enormously regarding cost. The full kit is the hammer, sear, disconnector assembly, selector and spring. An M2 converted to semi-auto only should still have the correct operating slide. The disconnector assy, selector and spring are the parts I usually make. I can do the other parts but it gets very expensive.
