The first gun with a rifled barrel (a rifle is any gun with grooves cut into the barrel to give the projectile spin) used by American forces was the Kentucky rifle, used in the revolutionary war.
Grooves can be on the outside of the barrel- called fluting- and they are cut with a milling machine. Grooves can also be inside the barrel- that is the rifling. It is cut by a special tool. The earliest rifling tool cut one line at a time, gradually getting deeper and deeper. Now a rifling tool called a broach may be used- made of extremely hard material, it is pulled through the barrel by a machine, and cuts all of the rifling in one pass.
The original factory barrel will have the name Winchester and the chambering of the gun stamped into it.The color is another tell, the color on the chamber should match the barrel exactly.Look at the joint between the barrel and the chamber, can you see any bare metal at the end of the barrel?A replacement will have to have had the threaded end of the barrel milled after it was blued to get it to fit right.
The gun barrel is the metal part that the bullet comes out of.
