What is the difference between an AR-15 pistol lower and AR-15 rifle lower?

The physical lower receiver may be similar, but the firearm's configuration and legal classification depend on how the receiver is transferred and assembled. An AR pistol configuration generally uses a short barrel without a shoulder stock, while installing a shoulder stock on a firearm with a barrel under 16 inches can create an NFA-regulated short-barreled rifle. Always follow current federal, state, and local requirements when configuring a receiver.
