ATI Alpha Maxx Pistol 5.56x45mm NATO 7" 30rd FDE - $329.99

While on paper this looks like a good deal for a decent looking AR pistol HOWEVER, I would never buy one of these all plastic firearms. A few people do not agree with me on the fact that over time, repeated pressures, heat and cooling cycles and environmental conditions all will eventually weaken and most likely warp the plastic components. The fact these also have plastic triggers and lower parts is cause for more concern. Literally just about everything including the buffer tube are all plastic..if the issues I address here were NOT a problem, why is it with every new generation they've had to add more and more metal to the stress points? It's physics...take a close look at the upper to lower fitment below the forward assist and you'll see poor fitment and a gap.
If your looking for a safe queen or something just to go shoot once or twice a year it'll probably be ok, but if your like me, someone who shoots a lot, I would look for a better option. Check out BCA, Prepper gun shop, Anderson, PSA and plenty others offering all metal guns around the same price range $300-$400.
