The Classic Army 5 Slot ARS4/URX4 is designed to be set on key modded panels and rails in order to have a set space for attachments, such as flashlights, lasers, grips, and other accessories. The shorter length cuts down on unnecessary weight, giving the user much more potential to move and attack with much more haste!
