Who uses them, are they worth it, etc.? It seems like a logical idea, but I've not run across them in wide enough numbers to suggest widespread use. When someone is building a "precision" upper, do they use them? If not, what's the difference in building a "precision" upper vs a "plinker", aside from quality of components? |
