 On firearms where the cocking handle is permanently connected to the bolt or bolt carrier, a dedicated device is not necessary as the bolt can be assisted forwards by simply pushing or tapping the cocking handle forwards.The forward assist is generally not necessary as a standard procedure on any firearm with the exception of the British L85A1.Having realized the frequency with which the firearm jammed when taken outside of the clean environment of the test range, the forward assist was implemented to save the operator the potential danger of aiming the rifle and pulling the trigger and the rifle not going off because the bolt is not fully forward (a safety arrangement called a "safety sear" stopping the hammer from being released and the firearm firing, because of the dangers of firing with the bolt not fully closed).
