I've owned a Harrington and Richardson U.S. Rifle M14, A Springfield Armory M1A, and a FAL clone made by Ishapore, the 1A1. I miss my M14. When I moved from Canada to the U.S. they wouldn't let me bring the M14 with me, even though it had been converted to semi-auto only because it still had the full auto receiver. I'm still heart broken.
I'm sorry for you, it would have broken my heart also.
