Abstract
A system and method of generating one or more perforations in a well casing while simultaneously restricting burr formation is provided. A perforating gun assembly includes a gun housing having an outer surface designed to engage the inner surface of the well casing. At least a portion of the outer surface of the gun housing substantially corresponds to the inner surface of the well casing. The position of the gun housing engaging the inner surface of the well casing restricts burr formation both upon the inner surface of the well casing and the outer surface of the gun during explosive charge detonation.
