Product Overview

Now shipping with our new custom Torx T20 fasteners!

G10 MLOK RailScales® - Our signature product and namesake, RailScales® are the industry leading solution to adding superior grip and heat protection on your MLOK 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.

Sold Individually

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.

    Excellent grips!

    Posted by Charlie on Nov 27th 2023

    Great quality and the service was excellent! I made an error on my initial order that wasn’t caught until after checking out. I emailed RailScales and got a quick response from an actual person that works for RailScales reassuring me that my order had been updated as requested. Very please with the product and makes my Sons of Liberty M4 fit and finish look as clean as you could possibly get. Will be doing business with RailScales in the near future.

    Love these grips, the hexagon pattern is very robust and grips like a charm. I didnt know what G10 was but after seeing the product I can see how strong they are. Thank you for the great grips and service.

    The best rail scales

    Posted by Jack Previte on Oct 5th 2023

    These guys just make better scales than other companies, period. Between the material, precision machining, and awesome patterns, there's not much not to like. And they continue to pump out additional lengths, providing more customization to the user.
