An in-weapon sensor enables electronic measurement of the firing pin indent force of a weapon system. The in-weapon sensor measures, either directly or indirectly, the indent force of the firing pin and communicates the information outside of the weapon to a data capture device. The data capture device provides a visual indication as to whether the firing pin indent force is sufficient or insufficient.

M4A1 Helically fluted gun barrel

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.
