G10 XOS-H™ in MLOK

(60 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 XOS-H™ cutout slot is compatible with SureFire Scout Light Pro lights (w/ MLOK mount) with end-user modification. Send an email to for modification instructions.

    Awesome product

    Posted by Mike on Jan 27th 2023

    I got one of these with the Karve P and was hesitant b/c of the price but I can say that I really enjoy the combo of the two. They feel great and sturdy and look good as well.

    Great handguard covers and heat dissipation. I bought the matrix amd they are very aggressive which is what I wanted. I have very large hands amd work with them so I tend to go very aggressive with my stippling. I can see these being uncomfortable for my wife's hands. My only complaint is for the price you pay, the portion on the sides where it's hollowed out for 1 mlok space is a bit giving, there's some flex in it which I wasn't a fan of. Maybe they are just my set... not sure.

    I would have dropped the rating a star for the price/cost but the quality, material, and precision manufacturing easily gets an extra few stars. I went with a four-slot XOS-H rail on the bottom with the Karve, and then two three slot XOS rails at the 3 & 9 o-clock and that gave me the perfect coverage that I wanted. Not thrilled with the price but I would certainly do it again simply for the quality and precision of the product and solid feel and texture they provide. I think I might have liked the "mini-dot" texture over the "honeycomb"

    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!
