In most handguns, the receiver, or frame, holds the magazine well or rotary magazine as well as the trigger mechanism. It is sometimes called the body of the firearm, while in the context of handguns (revolvers and pistols), it is often called the frame.
The receiver is often made of forged, machined or stamped steel or aluminium; in addition to these traditional materials, modern science and engineering have introduced polymers and sintered metal powders to receiver construction.
In strictly legal terms, in the United States the receiver is the actual firearm itself, and as such it is the controlled part (without which operation is impossible). Generally, the law views the receiver as that part of a firearm housing that has the serial number upon it. Thus, in the case of a firearm that has multiple receivers (such as the AR-15, which has an upper and lower receiver), the legally controlled part is the one that is serialized (the lower, in the AR-15's case).
