80% Lowers

We know that there are several types of 80% lower receivers available for AR or .308 builds. There are many different types of 80% lowers to choose from; raw, billet, anodized, forged or cerakoted. Each type of 80 percent lower provides its own benefits, but, ultimately, it depends on what you are looking for in your AR 10, AR 15, .308 rifle build.
