Those uppers are probably fine but I'd spend a little more and get a real lower, not that flimsy plastic crap. Those would be fine for a .22 build that I don't care about but I wouldn't trust one for a real AR.

Polymer Lowers are fine. Gun Envy modified a Frontier Lower and built a full auto M4 out of it. I think they have over 5k rounds through it and it is holding up just fine.

1/16 twist is good for .22

 

It's a measurement of how many inches it takes for the rifling to twist. So 1/16 means one twist in 16 inches which is a slow twist. Most AR's are either 1/7 or 1/9. 1/9 twist is good for lighter loads and 1/7 is good for heavier loads. With modern ammunition most people will say to just go with 1/7 for any .223 or 5.56, but if you were to use a .22 conversion you may have issues.
