Looks like the work of Warren Donnell (not sure the last name is correct) who was active around the Texas gun shows several years back. He had a stamp for everything, and was noted for building "USMC" M1icon Rifle match rifles. The 03-A3 did not get the full treatment as far as stamps, as he really loaded up the M1 Rifles.
Someone figures they got a bargain, as the Buy Now price was $3000.
