I have never seen a lower that was so "out of spec" that it couldn't be put together. So you might have to file on a mag catch every now and then.
The fit between the most expensive upper/lower will get loose. That's why we have the accuwedge and JP tension pin.
No reason to spend big $ unless you are just really particular, or plan on selling it.
