We are evaluating machine shops as a space to invest.

We have found a few machine shops out there who claim to have sales in the defense market but we are unsure if they are in a tiered supply chain selling to larger defense companies who then sell upstream to DOD, or if these machine shops sell direct to DOD; we believe the market consists of a blend of both.

Does anyone know any machine shops who sell direct to the DOD, possibly through the Defense Logistics Agency?
