What You Need to Complete Your Build

This is a stripped lower receiver—the serialized component that legally constitutes the firearm. To complete your AR-15, you'll need to add a lower parts kit (trigger group, safety selector, magazine catch, and springs), a buffer tube assembly with buffer and spring, and a stock of your choice.

Whether you're building your first AR or your tenth, Aero Precision's Gen 2 lower provides the precision foundation serious shooters demand.
