"Checked the crown and found two small chips and decided to try this kit. IT WORKS GREAT. It lapped out the chipped area and accuracy now is fantastic." - Customer Email

Rifling consists of grooves cut or formed in a spiral nature, lengthwise down the barrel of a firearm. The lands are the raised areas between two grooves. When barrels are manufactured, they start out as a solid rod of steel. A hole is drilled down the center of the rod and the rifling is then placed in the barrel. Tiny micro burrs will form on the barrel muzzle after repeated use or dropping the muzzle on the ground. This is a great way to fix or maintain the accuracy and integrity of the barrel crown. Rifle Bore Lapping is a much more involved processs and is not the objective with this kit.
