Start your build with AR15 lower parts kits from Del-Ton. Our Mil-Spec AR lower parts kits fit any Mil-Spec lower. Choose from a complete lower parts kit, an oops kit or a lower kit without a pistol grip. Find the perfect grip for your build on our AR15 accessories page. If you are after precision work, install a two-stage-trigger AR15 lower kit. Match this to a precision barrel and upper with match-grade ammo and you are in the 10-ring with every shot.
Putting a lower together is pretty easy. Hanging on to all those tiny parts, especially spring-loaded parts, is not easy. Get backup parts for those easy-to-lose springs and detents. Don't spend an hour trying to find that brass detent or that buffer spring. Grab another one from your AR15 lower kit. Build with confidence with Del-Ton's quality AR15 lower receiver parts kit.
