Abstract:
A charging handle includes a shaft, a front end that is operably coupled to a firearm bolt carrier, and a head that is located on an opposite end of the shaft from the front end. One or more ventilation features may be located in a first half of the length of the shaft proximate to the front end of the charging handle to prohibit exhaust that travels from the front end along the upper surface and/or side surfaces of the shaft from reaching the rear of the firearm and/or the head of the charging handle.

Claim (Index 17):
A firearm associated with a firearm specification, the firearm comprising:\n one or more features that restrict, reduce, or otherwise impede a flow of firearm discharge exhaust gases out of a muzzle of the firearm, wherein the one or more features include a firearm accessory and/or a barrel characteristic that is different than barrel characteristics of the firearm specification; and a charging handle to at least partially compensate for gas pressure associated with the one or more features, the charging handle including:\n a shaft having an upper surface and side surfaces that extend along a length of the shaft between a first end of the shaft and a second end of the shaft; \n an internal cavity located between the first and second ends, wherein the upper surface is located on an opposite side of the shaft as the internal cavity; \n a front end located at the first end, the front end configured to operably couple the charging handle to the firearm; \n one or more projections located at the second end, the projections configured to allow the charging handle to be pulled to charge the firearm; and \n one or more ventilation features provided in the upper surface and/or in the side surfaces, wherein at least one of the one or more ventilation features penetrates through the shaft into the internal cavity, the one or more ventilation features configured to impede a flow of firearm discharge exhaust gases along the upper surface and/or side surfaces from moving towards the one or more projections and/or redirect the flow of the firearm discharge exhaust gases away from the one or more projections.
