G10 XOS-H™ in MLOK

(49 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.

    Best forward grip products, bar none

    Posted by Brett Koleszar on Dec 14th 2021

    I use the Vendetta Precision VP-24 Hand stop in combination with the G10 XOS-H. It's by far my favorite forward grip combo. Super fast shipping!

    Can’t say much due to it not fitting my rail. I have Midwest rail and saw Midwest compatible and bought it without any thought. Lucky I only bought one as a test onto desired rail. Only thing I can rate is quality and that’s A+

    G10 XOS-H

    Posted by Ken N on Oct 2nd 2021

    My first impression of the XOS-H was its size. Although I knew the dimensions before I ordered, I’m glad I got the wider scales. Not a complaint, just an observation. Holding the scale in my hands, I noted how thin and light they are, yet they seem to have far more than enough integral strength for their purpose. The scales are sufficiently grippy. They are immaculately machined. The bevels for the M-LOK screws are perfect. No sharp surfaces remain, only a great honeycomb pattern. These are not only functional; they do add a cool factor to my AR. In my opinion, worth the extra money. I am a great believer in the saying, “If you don’t have the time/money to do it right the first time, you’re going to have to make more time/money to do it right the second time.”

    Worth it!

    I’m in Arizona so handguards can get hot even before you get a round off. Got the XOS-H in honeycomb with the Karve P for an AR pistol. These are thin, ultra light, add the grip I was looking for plus keep the heat away. My only complaint is now I know I need Railscales for ALL my platforms!

    Fantastic product, prevents heat transfer when you’re running your gun. Worth every penny.

    Super lightweight and worth the price difference from the polymer version. Fits on a rifle perfectly.
