AR Lower Receivers

The lower receiver is the serialized part of an AR-pattern rifle — legally it is the firearm, and everything else is a part. That makes it the starting point of a build and the component with the most paperwork attached.

Ceremony Arms carries stripped lowers for builders supplying their own lower parts kit, trigger and stock, and complete lowers assembled with fire control group, buffer tube and stock so you only need to add an upper. Forged, billet and polymer receivers are all represented, in AR-15 and AR-10 patterns.

Because lower receivers are firearms, they ship to a licensed dealer for transfer and are subject to background check, waiting period and any state-level feature or roster restrictions. AR-10 pattern lowers are not cross-compatible between manufacturers, so confirm the pattern your upper uses first.
