Abstract
An M4A1 helically fluted gun barrel is provided which increases sustained peak temperature levels for the barrel. This M4A1 helically fluted gun barrel incorporates multi-start variable pitch helical openings into the exterior profile of a standard M4A1 heavy barrel. The helical openings increase the outer surface area for heat dissipation, and also reduce weight as a further advantage.
