As far as DoD buying Plainfield carbines for DoD police, I'd have to see some documentation on that one. When CMP sold carbine barreled receivers several years ago, the only provenance was that El Salvador returned them along with whatever MAP carbines they returned.
On the way back machine https://web.archive.org/web/20060414...es/carbine.htm not much information was provided about the 176 Universal and 256 Plainfield receivers. All of these receivers, to include the commercial non-military Plainfield and Universal, were transferred to the CMP by the the US Army.

At $50 each, I ordered two Plainfields and a $225 'S''G' receiver that was in the IP serial range.
