AoA AR15 Lower Parts Kit – Complete

100% Made in America

Arm or Ally AR15 Lower Parts Kit contains high-quality, 100% American-made components to help you build a custom AR15 from the ground up. Each kit is expertly manufactured to Mil-Spec dimensions to ensure the highest quality and correct component interface. No polymer or MIM components in our kit, just the good stuff you can rely on!

This kit includes all small components to complete a lower receiver. If you don’t plan to use the A2 grip, we offer this same kit without the grip or trigger guard, as well as a stripped-down AR15 LPK for those builders who want to use their own trigger and grip.
