  • Maximum Venting: The rail’s design maximizes venting for heat dissipation, reducing the overall weight while maintaining its rigidity.
  • Proprietary Barrel Nut: The 2.25" long barrel nut increases surface contact with the receiver, ensuring a straight and true platform, improving accuracy and zero repeatability.
