Receiver FAQs

Is a lower receiver treated as a firearm? Yes — a serialized receiver or frame is legally a firearm, so it ships to a licensed FFL dealer and requires a 4473 and background check.

What do I need to finish an AR-15 build? A lower parts kit, buffer tube assembly or stock, and a complete upper receiver group — all available in our AR parts and accessories category.

Forged or billet lower — which is better? Forged lowers are stronger per dollar and lighter on the wallet; billet lowers offer tighter tolerances and custom styling.

Pick your receiver, add your parts kit, and start your build today.
