Ported Barrel

Mag-na-Port brand barrel porting.

Ported barrels - A barrel with a series of holes or slots drilled near the muzzle. When a ported barrel is discharged, gasses moving violently down the barrel hit the forward edge of the holes and pull the gun forward off the shoulder, reducing felt recoil. Porting holes, when cut along the top of the barrel also work to depress the barrel under discharge, counteracting muzzle jump. Ported barrels may provide some benefit to the shooter, but the sideways blast of gas is somewhat obnoxious for others nearby.
