Firearm Parts and Components
Whether you are building from a stripped receiver, replacing a worn part or upgrading a factory gun, Ceremony Arms carries the components that keep firearms running and let you tailor them to how you actually shoot.
Our parts catalog covers stripped and complete upper receivers and lower receivers for the AR platform, barrels and choke tubes in common lengths, profiles and chamberings, bolts and bolt carrier groups, pistol slides and frames, barreled actions for bolt-gun builds, caliber conversion kits, suppressor and silencer parts, and the small components that are easy to overlook until you need them — snap caps, trigger locks and safety hardware.
Before you order, confirm fitment: receiver generation and takedown pin diameter on AR builds, thread pitch and gas system length on barrels, and slide-to-frame compatibility on pistols. Some components are regulated differently from accessories and may require transfer through a licensed dealer depending on your state. If you are not certain which category a part falls into, ask us before you check out.
