So I was doing some looking in the FRT system about this because I was bored at work. All the actual Armalite entries are either full-auto, converted-auto, or restricted. I found out this is because even Armalite began making "AR-10s" that were just upscaled AR-15s as early as the 1960s, and they themselves never made a semi-auto AR-10. The only company that made semi-auto only AR-10s was a Dutch company with a contract from Armalite. They basically did all the work on the AR-10 to improve it and make it work, and Armalite completely ignored all of it. There is precisely one FRT entry in the AR-10 family that lists as non-restricted, it is the Armalite AR-102 Sporter by Artillerie-Inrichtingen, Zaandam, entry number 161646. Every single other entry is either converted auto, full auto, or restricted as an AR-15 variant.
This is probably the gun NEA is basing this gun on, and it's probably also why they chose the name they did. If that's the case, and it's for all intents and purposes the same as the old AR-102, then it should indeed be NR.
