Start a new build or simply swap out an old lower for a new one on your current AR build with our huge selection of in stock lower receivers. We carry AR-10 and AR-15 stripped lowers and complete lowers in a wide range of designs, colors and variations. Check out our line of 80% lowers for those that would rather finish the final 20% themselves. The lower half of your AR is a vital part of the gun and butts up with the upper and the rest of the firearm. Select from poly, aluminum, and other materials which will change the weight and overall feel of your build. If you’re going with a stripped lower, rather than a complete lower assembly, be sure to check out our range of lower parts kits, trigger assemblies and the rest of the stripped lower. We carry lowers from the biggest brands including ATI, Anderson, Aero, Spike’s, Rise, CMMG, 2A Armament, and many more.
