What Is a Match-Grade Barrel?

A match-grade barrel is fit for use in competitive shooting matches. Though there is no specific standard for qualification as match-grade, a match-grade barrel generally has a better-than-average potential for accuracy and may feature one or more custom modifications.
  1. The Bull Barrel

    • One example of a match-grade barrel is the bull barrel, or one that has a diameter equal to its length. Because of the barrel's thickness, it has the advantage of increased stability, but the disadvantage of added weight.

    Rifling

    • Bull barrels often feature custom rifling for added accuracy. The rifling in a barrel is the series of grooves made in the bore, or tube, of a barrel. The grooves cause the projectile to spin as it travels down the barrel, increasing the accuracy of the shot. Even slight adjustments in the pattern, size and texture of the grooves can have a considerable effect on a weapon's precision.

    Porting Holes

    • Match-grade barrels may also have porting holes, or holes drilled into the barrel with the purpose of discharging the eruption of gas that accompanies a gunshot. When this gas is allowed to escape, recoil of the firearm is reduced considerably, making for a more accurate shot.
