Again, technically? PAR, MV/MH, not an AR because ARMALITE didn't design them.
Legally? Not a restricted AR variant, because ATRS specifically designed an AR variant to not be an AR variant, I don't have to say that, they did. Troy took an AR10 and butchered it into a pump action, and called it a proprietary design.
Just to confuse things a little...
Arguing over features and who designed it is moot. The features have nothing to do with the AR-15's restricted status. To clarify what I mean, use the MV, it's
not an AR-15. It's a proprietary AR-15 if you like, the numbered pieces can't interchange, but that's it, so why can one be NR and the other R? It's all in a name, go look at the list of 12(x) firearms, it includes pretty much ALL "Black Rifles" available in the late 80's/early 90's

(, and it was glorious). That included the AR-15, but it's a good dog so they didn't pull it's teeth, they just muzzled it with a restricted status based on it's name, not the design. Keeping in mind that if a rifle is a mechanical clone of an AR-15 the numbered bits will likely work perfectly together, and therefore a variant of the AR-15...which although bothersome is a much better outcome of something like being a variant of the (insert name of pretty much every semi auto with a detachable mag and pistol grip pre-1990ish here). All of them on indefinite house arrest since the mid 90's by OIC.
The point is it's all in the name, not the features or design. NEA is arguing the rifle is based on a design that predated the AR-15 and therefore can not be a variant, and must be classified on it's own merits, a semi-auto rifle with an 18.5"+ barrel who's numbered bits can't interchange with a rifle listed in the OIC as prohibited/restricted. Assuming that the argument, I can't be the child of my child wins the day, it has to be NR.
