The Valken Tactical VGS (Vertical Grip System) has been specd and
designed for use with 1913 Picatinny railed hand guards. The VGS is a
minimalist, light weight, cost-effective grip that also has light/laser
pressure pad/cable management. The bungee cord is there to support the pressure pad on your light or laser for easy attachment around your RIS.The shape of the ergonomic design
allows the shooter to use it as a traditional grip, yet also encourages
more dynamic grip techniques for several styles and body mechanics.
