Abstract
An attachment for a gun has a plurality of pressure relief ports positioned on the barrel that create pressure differentials which impart a rotary motion to the projectile which stabilize the projectile in its ballistic path. The pressure relief ports allow the gun to spin stabilize the projectile without the provision of rifling in the barrel. The pressure relief ports can further be arranged to reduce recoil and barrel rise associated with firing the gun.
