Anyone and everyone, my pic request is for pictures of original heel markings of M14 national match rifles and XM21 rifles. If by chance any of you guys see any in the museums or NG armories, or wherever, please take pics of any heels that are marked with the NM or the XM21 markings. I will continue to bump this page up for as long as I can. Please contribute.I'll start with the West Point XM21, and one I think is from the Australian museum so you guys know what I'm asking for. TIA.
