John, that handguard was a real RBR handguard someone shortened about 2 inches, but left the barrel clip intact. I got it for $35. I now need a crackerjack wood worker to restore it. 100% RBR now - no repro parts whatsoever.

I've heard many people extoll the woodworking virtues of Rick borecky. You might want to contact him. I know he has lots of scrap stocks and handguards to select from.
