AR15 Upper Receiver — Billet, No Finish

Outerwild's in-house machined AR15 billet upper receivers are the perfect complement to our billet lowers. Machined from a solid brick of 7075-T6 aluminum, hand deburred, and tumbled then shipped raw for you to add a finish. Accepts all Mil-Spec components and fits all Mil-Spec dimensions lower receivers. We ensure that every upper is well within spec and will function perfectly for your build.
