The Outerwild in-house machined billet lower receivers are the perfect foundation for your custom kit build. We start with a solid billet of 7075-T6 aluminum and then precisely machine all of the critical features and dimensions of the lower to ensure that every receiver is perfectly in spec. We then broach the magazine well for a perfect magazine fit, hand deburr, tumble and hard coat anodize. The result of our time and attention to detail is a billet receiver that will last you a lifetime and guarantee you a worry-free and quality build. These receivers accept all Mil-Spec components and look great with both a Outerwild billet or forged upper receiver.
