I remember when those H&K aluminum magazines were like $60.00 per magazine, now they can be had for $5.00.

By chance, with your original AR10, do you remember who the maker/marketer/importer was? Armalite never made a semi-auto AR10, but there were a few companies who brought in parts kits, mostly from Denmark and then made lower receivers and assembled rifles out of them. Also, which magazine did your AR10 have, steel, aluminum or both?

And do you remember if yours was early style with the big can style muzzle break, or late style with a flash suppressor more like a modern AR? Black or brown furniture?

Reason I ask is, I worked for one of the companies who made AR10's in the '80's. We made up a grand total of 1,000 rifles and sold them. I have NEVER seen one since we sold them...kinda makes me wonder if they just fell into a black hole somewhere.

The one's we made up were absolutely PERFECT, I'd love to see one again. You don't by chance still have yours do you?
