The Element Armament machined AR15 lower receivers (billet) are the perfect foundation for your custom AR15 build. It starts as a solid brick of 7075-T6 aluminum precisely machined to include all of the critical features and dimensions of the AR15 lower in a single operation, ensuring that every receiver is perfectly in spec. Afterwards, the magazine well is broached for a perfect magazine fit, hand deburr, tumble and hard coat anodize. The result of this time and attention to detail is an AR15 lower receiver that will last you a lifetime and guarantee you a worry-free and quality build.
