What is a stripped lower receiver?

A stripped lower receiver is the part of an AR-15 rifle that houses the trigger group and magazine well. It is made from aluminum and has a series of holes and slots that allow for the installation of the trigger, hammer, springs, and other small parts. The term “stripped” simply refers to the fact that this type of receiver does not come with any of these parts installed.

Many gun enthusiasts enjoy building their rifles from scratch, and a stripped lower receiver is essential for doing so.
