G10 XOS™ in MLOK

Product Overview

XOS™ in MLOK - An evolution of our traditional G10 machined RailScales®, XOS™ Scales are a 3-sided solution that offer twice as much grip surface in the same mounting footprint. Adding a 135º “wing” on each side of the panel allows for the XOS™ to tightly wrap your rail, and provides one seamless grip area for unparalleled handling and heat protection. 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 agianst heat transfer. Available in four popular textures and varying lengths, these scales allow for multiple setups no matter how much rail space you have available. 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 scales to our lineup.

Great grip

Posted by Chris on May 19th 2022

These rail covers truly exceeded my expectations and are most certainly worth the price. The Matrix pattern XOS covers fit great on my Radian Model 1 and give me such great grip on the rifle while reducing heat transfer to my hands better than any covers I've tried before. Customer service was also very helpful as I was unsure if the covers would fit my rifle but I got clear and precise answers in a timely manner. Last thing I'd like to say is that I am very pleased with the shipping, they were shipped the night I placed my order and I received them in 3 days with no delays or problems. Definitely will be coming back for more when I get another toy to play with. Excellent product

G10 XOS

Posted by Anthony Quintero on Mar 23rd 2022

I was interested in finding something lightweight and functional. I wanted something that stood out and was different from a majority of other options. I came across Railscales at GunsLA in Burbank,CA and wanted to have that on my build. I emailed with concerns on fitment for my Lantac handguard and Derek emailed me back saying that it should fit my handguard and that if it didn’t that I would be able to ship back at no cost and order another that might fit. It fit beautifully and the function and comfort are worth having on any build or rifle. I would definitely recommend because the function is as good if not better than how they look.

Worth the Money

Posted by Alexander on Mar 3rd 2022

Super grippy, stops heat, perfect fit on my Geissele mk14 rail. G10 is very durable to abrasion, will last forever and the included hardware comes with tooling and locktite for install. Aesthetic AF, worth the money.

Easy installation, great fit, and just the right amount of aggressive stippling. Also, provides nice heat mitigation after long sessions or mag dumps.

Love these Scales!

Posted by Eric Moss on Jan 6th 2022

These are pricey, but fantastic scales. They do a fantastic job of giving grip and a heat shield on my 11.5" railing.

Best grip panel

Posted by Trevor Martel on Dec 25th 2021

The best. Thought I would try one of these to see what all the fuss was about. Now I know, truly the best and they're all I'll use from now on.

G10 XOS-H

Posted by Matthew Gore on Dec 21st 2021

Railscales delivered AGAIN with quality products as usual. I'm a long time customer with them and have never gotten a product I wasn't completely satisfied with. The G10 XOS-H railscales fit perfectly on my PWS rail and have a very sturdy, durable feel. Railscales always exceeds my expectations with their products and always delivers the highest of quality. Thanks again Railscales!
