Building an AR15 lower is easy enough. The hard part is keeping the tiny springs and detents from flying across the room. Del-Ton offers AR15 lower parts by the piece. Order extra detents, springs, pins and more to have exactly what you need precisely when you need it. Create your own AR15 lower receiver parts for future builds or to sell to other builders. Make repairs at any place and any time.

Improve your current AR with enhanced parts like binary triggers, ambidextrous safeties and expanded trigger guards. Drop that mag with either hand with an ambidextrous release. Extended takedown pins make field stripping a breeze. All Del-Ton's AR lower parts are Mil-Spec and will fit any Mil-Spec stripped lower receiver. You can buy lower receivers from Del-Ton as well. Don't worry about tolerances being just a hair off. Our precision manufacturing means all the lower receiver parts fit precisely.
