G10 XOS-H™ in MLOK

(56 reviews) Write a Review

Product Overview

XOS-H™ in MLOK - This variation of our traditional G10 XOS™ Scales offer the same great features, but add an accessory cutout that partners seamlessly with other RailScales® products to give you multiple modular options that best fit your shooting style. While most commonly used at the 6 o’clock position with our Karve®, Karve-P®, Anchor®, or RSB™, the XOS-H™ will also fit our QDX™ Sling Mount as well as additional future RailScales® products to mount at various positions based on use. CNC machined out of high quality US made Black FR4 or our brown terrian colored TerraCore™ (commonly known as G10), our scales provide an umnatched barrier against heat transfer. They will accommodate most popular handguard rail systems, however please check the specs below to insure these will fit yours. 

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™ XOS-H scales to our lineup.

The XOS-H™ cutout slot is compatible with these RailScales® products.

    The best out there

    Posted by Austin Gebben on Jul 30th 2022

    The main reason I got this was because my gas block wouldn't allow me to mount a “standard 3 slot panel. This definitely exceeded my expectations. When you c-clamp with this is unlike any other rail panel. You get maximum control and I would expect nothing less from railscales. Make sure to get the matrix like I did if you maximum grip with or without gloves.

    Again, I have gone with the honeycomb. Adds some grip! Recently outfitted two AR platforms with the new FDE colored scales. Loving these as they protect hands from heat if running supressed systems. Thanks!

    G10 XOS-H

    Posted by Ricco Feliciano on Jul 2nd 2022

    RailScale’s G10 XOS-H is a great addition to any naked M-LOK handguard. Instead of constantly replacing ratty fire-proof wrapping that succumbs to wear & tear, the G10 XOS-H is an excellent addition, if not replacement. On gloveless days & running a hot barrel, you can still go the distance even in high volumes of range work.
