The Anderson Manufacturing AR-15 complete lower receiver is a ready-to-assemble platform that puts you one upper away from a finished rifle. Built from aluminum with precision manufacturing, this M4-pattern lower arrives with the lower parts kit and buffer tube assembly already installed—so you skip the tedious assembly phase and get straight to the range or field. It's the same lower Anderson uses in their own AM-15 rifles, which tells you something about the confidence they have in the design and build quality.
If you're building your first AR-15 or your tenth, a complete lower receiver handles the regulatory and mechanical heavy lifting. The semi-auto action is chambered for 5.56 NATO or .223 Remington, giving you flexibility in ammunition choice. The anodized finish protects the aluminum against corrosion, and the included 6-position buffer tube kit lets you dial in the stock length to your preference. A standard M4 grip and open trigger round out the package—familiar controls that need no introduction to anyone who's shot an AR platform.
This lower is spec-compliant and ready to accept any standard AR-15 upper receiver assembly. Whether you're planning a lightweight varmint rig, a hunting rifle, or a tactical build, starting with a proven Anderson lower gives you a solid foundation that won't nickel-and-dime you with fitment surprises. Note that an FFL is required to take possession of this lower receiver.
