Sold Individually
XOS® in M-LOK - An evolution of our traditional G10 machined RailScales, XOS Scales are a 3-sided solution that offer twice as much grip surface in the same mounting footprint. Adding a 135º “wing” on each side of the panel allows for the XOS to tightly wrap your rail, and provides one seamless grip area for unparalleled handling and heat protection. CNC machined out of high quality US made Black FR4 or our brown terrian colored TerraCore (commonly known as G10), our scales provide an unmatched barrier against heat transfer. Available in four popular textures and varying lengths, these scales allow for multiple setups no matter how much rail space you have available. They will accommodate most popular handguard rail systems, however please check the specs below to insure these will fit yours.
TerraCore complements our line of Terra Bronze anodized and FDE polymer components as well as third-party branded tan anodized or Cerakoted rail forends. Unlike coating or painting options, our TerraCore scales are colored throughout and remain so after CNC machining operations. Offered in the same patented textures and resilient heat protection options you've come to expect. We are excited to introduce TerraCore XOS scales to our lineup.
