KRG X-ray Chassis 700SA Black Large Grips



Kinetic Research Group’s X-RAY has similar ergonomics to the KRG’s Whiskey-3 chassis with more adjustability to the length of pull. KRG kept all the same features that shooters want and kept the production cost down to make this great hybrid aluminum and polymer chassis.

  • Mounting holes will take L2 Picatinny rails, Tripod Mount, etc.
  • Access hole for action mounting screw (allows the action to be removed without the forend having to be removed)
