ANATOMY OF BARREL CROWNING, HOW IT WORKS WHAT IS BARREL CROWNING?             Barrel crowning is the process of machining, smoothing, and shaping the muzzle end (mouth) of a firearm barrel to enhance accuracy. It creates a recessed area where the rifling ends slightly behind the barrel’s outer edge .
