A blank barrel, or a Barrel in White means there is no machining done to allow you to INSTALL it right in a rifle.
You have to machine the barrel to fit what ever rifle your going to install it in.
YES it does have rifling and some are choked and some not, and they come in differnt diameters .63 is a 16 mm barrel,
.59 is 15 mm a gamo size barrel.
And choke means the muzzle end of the barrel is Smaller than the breach end, this squezzes the pellets to the same size when they exit the muzzle.
