TerraCore™ RailScales® in MLOK- New for 2021: Our popular line of RailScales® are now offered in TerraCore™, our brown terrain colored FR4 source material. TerraCore™ complements our line of Terra Bronze™ anodized and FDE polymer components as well as other brand 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 heat protection options we’ve built our brand on, we are excited to introduce TerraCore™ to our lineup.

RailScales® are the industry leading solution to adding superior grip and heat protection on your MLOK handguard. CNC machined out of high quality US made G10, our scales established the machined scale concept, and remain at its technology forefront. We offer patented textures, and multiple lengths to allow our customers to truly customize their weapon for the task at hand.

    Terracore Scales in mini dot

    Posted by Greg on Oct 12th 2021

    If you’re here, you likely want to know if these rail covers will do a good job in adding traction and heat protection . I mean, you already know how badass they look, but how do they FEEL/FUNCTION? Well my dear boy, I’ll tell you. I shoot primarily suppressed, and at a certain point with a bare rail, this usually means I need gloves to keep going. These not only offer excellent protection from a hot rail, but they also provide tactile feedback for your grip and where on the rail your hand is are resting. This is especially helpful when running drills that require removal of the support hand. All of my rifles have rail scales on them, and I wouldn’t have I any other way.
