Forward Assist   

Unlike the gas system, gas block, and gas tube, a forward assist is not a necessary component/option of an AR-15 rifle or any AR-platform rifle models. However, like the flash hider, having a forward assist is a bonus to others. It may not be necessary, but something like this could help by allowing a short chamber in the upper.
