In firearms, the term is used to refer to ammunition and gun parts that are designed and manufactured in such a way that they have a relatively narrow tolerance and high level of accuracy.
For instance, the Heckler & Koch Mark 23 weapons system is considered so specifically tooled for combat that it is match grade, one primary reason that the pistol and its components were selected by the United States Special Operations Command (SOCOM) for service.
[3] Manufacturing match grade ammunition and other parts requires extremely tight tolerances and quality control.
It is not unusual for match-grade ammunition and components to cost ten times more than comparable non-match equivalents, owing both to the increased labor expended in creation and much more rigorous testing.
[example needed] Match grade ammunition is often subjected to higher randomized testing to ensure consistency and accuracy, reducing the statistical likelihood of a dud round.
