The AR15 charging handle we're all familiar with was actually an afterthought when the original design of a trigger shaped handle under the "carrying handle" turned out to get too hot.
The AR15 charging system actually turned out to be a good solution in regards to heat mitigation and to keep the weapon sealed against the ingress of dirt and debris.
While the standard charging handle is sufficient, there is actually a lot of room for improvement. While it seems like this would be a relatively insignificant change, it actually is not, and we discuss that in this video where we've chosen to standardize on the Geissele Super Charging Handle for the WWSD project.
