M14 Elevation Pinion Assembly

I bought 3 of these expecting them to be M14 parts as listed ,No where does it say they are reproductions in the AD it says M14 Elevation Pinon Assembly WMI marked pinons are out of Taiwan, Wayne Machinery They make parts for Commercial rifles only the other two were unmarked repos also they look like Fulton Armory ones,These are not USGI pinons
