Prior weapon charging systems involved cranking assemblies that require an operator to turn a crank multiple times in order to achieve the stroke needed to fully draw back the bolt on the Mark 19 grenade launcher. These systems are time consuming and take significant effort to operator. Space is very limited within a turret of an assault vehicle, and some of these previous systems place the charging system in line with the gunner's hip which results in loss of space and creates the possibility of damage to gear and personnel.

Naval Surface Warfare Center, Crane Division (NSWC Crane), has developed and patented a system for charging the Mark 19 grenade launcher with a cranking system that fully charges by turning the handle less than one full revolution. Additionally, the cranking system is moved above the turret ring, directly behind the weapon, and out of the way of the operator.

-Less risk of injury
-Increased available space
-Decreased time and effort
