The Kinetic Research Group Arca Rail Heavy 9.5" Steel Black Nitride is a purpose-built accessory that adds Arca-Swiss rail functionality and extra mass to your KRG Whiskey-3, X-ray, or Bravo chassis. Machined from steel and finished in a black nitride treatment, this rail is designed to deliver consistent stability and smooth accessory movement along the length of the chassis.

This model is ideal for precision rifle shooters who want more flexibility in bipod and accessory placement while benefiting from added weight for steadier shots and faster recovery between impacts. The Arca interface allows quick repositioning of clamps and bipods during stages, making it well suited for competition, training, and dedicated range use. Kinetic Research Group’s focus on thoughtful chassis design and practical innovation is reflected in the rail’s robust construction and versatile mounting pattern.
