THE IMAGE ABOVE IS A PAID ADVERTISEMENT Typically I wouldn't buy a billet lower, but this one is going to be my SBR lower and I was going to get a forged one custom engraved w/ Texas on the side. After all is said and done its just about as much as the LaRue lower. |

Cannot load pictures tonight but I received my stamp for a Larue lower today. Pinned on a BCM forged upper and the fit is just fine. I would not hesitate to put a forged lefty upper on that lower.

I don't want to come off as a douche here, I'm just trying to save you some $.
Billet this or that is marketing hype. Billet is a term for material stock, or sometimes the shape of the stock. It has absolutely nothing to do with the strength of the part made from it. That is determined by what grade of material, and any hardening that has been done to it. For example, AR lowers are usually made of 7075-T6 aluminum. 7075 is the grade of aluminum. T6 is the hardening process applied to the material. That is what determines how strong or durable your part is, not what shape the stock was that it was machined from. |

Generally speaking, a billet upper or lower will actually be a bit weaker than a forged equivalent even if they are made of the same alloy and temper. This is because the grain structure of a forging is superior than than a homogenous blob of hot rolled aluminum bar or plate stock. |
