It has gone through the roof over the past year. I use to see them for half the price as a billet aluminum lower and now they are more expansive.
Why the hate? The polymer used by a good manufacturer is a better grade polymer and goes through more rigorous testing then the polymers used by some of the top selling polymer handguns (like Glocks and XDs).

Because they will still break. Handguns are not subjected to the type of impact/ resistance/ and continued forces that the Buffer tube subjects on the lower receiver. As it is the most Fragile part of the design.
Will they break on shot 15? NO? But they will ultimately break.
