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.

    Great product

    Posted by Zach on Jul 1st 2020

    I ordered the XOS Matrix 4 slot. It arrived extremely quickly and was very easy to install. I had a pic rail on the forend of my M1A and it was obtrusive and uncomfortable. I came across these the other day and knew they would work great. The rifle sits in my support hand much more naturally with the XOS in place of the rail. The texture is adequate, but not abrasive to your hand. The mounting process I used was not average since my chassis system is set up for Picatinny. I had to make a trip to the hardware store to grab some 8-32 thread T-Nuts that matched the supplied m-lok machine screws. I loaded my rifle up on the drill press and punched the Picatinny mount holes out so that the T-nuts fit snugly into the stock. At that point I simply used the supplied screws and mounted the piece snugly to the stock. I will watch the setup as I shoot the rifle. I might need to epoxy the T-nuts to the stock if it loosens any at all. I’m not overly worried though. I will definitely recommend these to my friends. I like the sleek look they give my rifle. The days of huge quad rails with garbage everywhere are long gone. I’m glad I found a way to cover unused rail space. Thanks for reading, I hope this helps someone.

    I really like the grips a lot, I feel like they are kind of pricey for the amount of material that you receive but overall very pleased w this product.

    Scales

    Posted by Sir Erik The Wise on Jun 17th 2020

    Use these on my BCM. They keep my hand safe while the rifle builds up heat. Provide very good grip too. Pretty much everything you need while adding a badass look.

    XOS Rail Covers ROCK!

    Posted by Long Nguyen on Jun 2nd 2020

    Just put a couple 3 slot XOS covers on my POF 12.5” and could not be happier. These exceeded my expectations as they now allow me to have a broader footprint for my grip. The mini dot pattern is just the right amount of texture too. Worth every penny!

    Very good product and very well made. It is a quality product that hits right to your rail and is not bulky and is very light. They also provide excellent texture for grip. Two thumbs up!
