The hand guard looks A1.
A ruler-on-the-screen says that the stock looks more A2 length than A1 and the butt stock looks like it's fully textured like A2, but I could be wrong on those.
Can't see if the flash hider has a hole on the bottom (A1) or no hole (A2).
The receiver is A2: the rear sight has an elevation adjuster, the forward assist is round rather than teardrop, there's a shell deflector behind the ejection post, and the slip ring is tapered rather than parallel. I can't see if there's a finger groove on the grip, but I'm guessing that there is.
[UPDATE] Oh, this one?

Yup, butt, stock, grip and flash hider are all A2. The only A1 thing that I can see on there is the hand guard. "A1 style receiver. Perfect for re-enactment [and] mil-sim", the cheeky buggers.
Now, I'm sure someone will out-nerd me (front sight post profile?).
