1. Why did they make this? What was so compelling about the redesign that they needed to change the NC22 they were making? (which is awesome)
2. Does the upper have anything proprietary about it - other than the slickside and small exit hole? As in - can you drop this into another standard upper receiver (something the NC22 would not do.)
3. Does this use standard AR charging handles, or is it some proprietary handle like the NC22 used? I HATE that I cannot use the Raptor on my NC22.
4. Does this use a standard barrel nut design like the NC22, and can take any standard AR handguard?
5. Does this upper work with any trigger, hook or rounded, two stage match, whatever, like the NC22 did?
6. Will this upper work with the Redi-Mag magazine adapters, which allowed you to use a S&W M&P 15-22 magazine. The NC22 was not compatible with this configuration.

Sorry for not responding sooner.
There's a lot of that info and other info in the
instruction manual.
To directly address your questions -- the upper is essentially a standard upper, but modified with the smaller ejection port. Everything will swap over to a standard upper if you chose to do so. Proprietary handle on this as well (which is my major gripe about the design), though it does use standard latch hardware, so you can at least add a larger latch. Standard barrel nut.
The trigger situation is hit or miss -- the firing pin channel is higher in the bolt than a standard AR, and Nordic advises not using any FCG with a hammer with an angled strike face, as it may cause damage to the firing pin.
Not sure on the Redi-Mags, as they aren't a product I've used, but I'll try to get some info on that for you.
I don't really know the exact motivations behind going to this over the NC22. I know the NC22 had a LOT of teething issues and, while those issues to my knowledge had been worked out satisfactorily, I suspect it may have just been to produce something that wasn't sharing that heritage.
