Product Overview

Sold Individually

G10 M-LOK RailScales® - Our signature product and namesake, RailScales are the industry leading solution to adding superior grip and heat protection on your M-LOK handguard.  We established the machined scale concept, and remain at its technology forefront. 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. We offer patented textures, and multiple lengths to allow our customers to truly customize their weapon for the task at hand. Fast and easy installation, thin and lightweight construction to streamline your rail, and functional and visually appealing options continue to make RailScales the most sought after option for completing your build.

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 scales to our lineup.

    G10 grips

    Posted by Unknown on May 24th 2024

    These are the finest grips available! Extreme attention to detail in fastener technology with the torque without a wrench markings and pre-applied loctite are but one instance that distinguishes this product. These are user friendly in adverse conditions.
