Abstract: A choke to be used with a muzzle of a gun may include a housing which may include an inner surface and an outer surface, and the housing may include a substantially central bore. The inner surface may inwardly taper at the distal end of the choke, and the inner surface may include a first depression having a first dimension. The inner surface may include a second depression having a second dimension, and the inner surface may include a third depression having a third dimension. The inner surface may include a fourth depression having a fourth dimension, and the first dimension may be substantially equal to the third dimension. The second dimension may be substantially equal to the fourth dimension.
