This adds a greater degree of safety and versatility. Held in place by an internal spring, the Night Manager sling mounts onto the shotguns forend. By adjusting the two Picatinny Rail sections, the shooter is able to control the night manager to where it needs to be for the perfect shot. The shroud, which is part of the rail system, can be rotated to where the shooters preference is. The Night Manager is made from steel and aluminum, including the follower, spring and follower tube. An extra follower is provided for handguns with a rotary magazine tube follower.
