Billet isn ' t weaker in that area , though . Forged is stronger because it aligns the grain of the aluminum with the shape of the final product . Billet is machined from a forged blank . Areas where the product align with the grain of the blank will be just as strong as forged like this spot . Areas that don ' t like the buffer tower will be weaker . This is no more likely to happen on a billet lower . What is more likely is to break the lower at the buffer tower while mortaring to clear a malfunction . <| sep |> No bondsman out here , at least not on that 10 % model <| sep |> Agreed . These seem to be the least likely type of volatiles to cause throat irritation . Although , avoiding them is perfectly reasonable , if you want to avoid buttery flavors .
