Sold Individually

XOS® in M-LOK - 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 against 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. 

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.

    G10 XOS-H , G10 XOS

    Posted by Thomas Olson on Feb 1st 2021

    Excellent grip, with or without gloves, rain or shine. Excellent product from excellent company. I was recently informed the XOS-H will accommodate both the Karve and the Anchor if you want to switch the two out depending on application.

    Expensive, but great product

    Posted by Michael on Jan 28th 2021

    I bought this after reading about them. Never heard of railscales before. So overall, its very sturdy and well made. Its made of a patented material of theirs which looks and feels like some type of fiberglass/plastic material. I got the matrix design and its an aggressive pattern. A little rough on bare hands, perfect when using gloves. Only downside is cost. Maybe cut out the super fancy box it comes in or find some other way to bring down the price to make more people interested. Fits my midwest G4M mlok rail perfectly.

    Perfection

    Posted by Patrick on Jan 25th 2021

    Was a bit nerves to order the XOS and XOS-H for my Armalite AR10A after not seeing it on the compatibility list. Decided to go out on a limb and order and I’ve got to say they fit perfectly on the Armalite M-LOK rail. Best grips I’ve ever put on a rifle and will definitely be ordering from you all in the future. Great product!

    4 slot matrix m lok

    Posted by Dylan on Nov 18th 2020

    They fit very very well on my bcm rail, look great. The matrix design is fairly aggressive so that’s something to be aware of with this pattern. I like it, it gives a really solid grip. I can not say how they hold up to eat and abuse since I have only put them on the rifle and haven’t been able to test there durability or how well they keep heat away from your hands but they cover the rail all the way around if the you get three rail covers for each side of open rail. Price is a little much but they seem to be worth the money and very well made.

    Great Product

    Posted by Jonathan Fincher on Nov 16th 2020

    I recently purchased the XOS covers after months of researching and trying to decide between the Rail Scales and other brands. I finally pulled the proverbial trigger and ordered and couldn't be any happier. I placed these on a Primary Weapon Systems MK111 Pro upper and the fitment was fantastic. There is about 1/8 of an inch between the covers, and they lock up nice and tight. I like them so much, I am ordering another set as well as the Karve. Will definitely continue to outfit my guns with these, and would highly recommend to anyone who may be on the fence.

    Top Quality

    Posted by Christopher A on Oct 27th 2020

    I purchased two G10 XOS in the mini dot pattern. They fit perfectly, and are easy to install. They even include the Allen Keys for the install. They are very very log weight. They feel great in my hand. I want to order three more in the future.
