Accurizing is the process of improving the accuracy of a firearm or airgun.
For firearms, accuracy is defined as the ability to hit exactly what one is aiming at. Further, accuracy and precision, or the ability to hit the same place over and over again in a repeatable fashion, are the goals of accurizing.
