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 45 degree “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. 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

    Best Rail Covets out there

    Posted by Stephen Z on Sep 20th 2021

    Fit my LMT perfectly and feel great. Also keep the heat shielded. Look awesome and Customer Service was also great. I buggered up the screws on a set and they sent replacements at no cost on my next order. Much appreciated!

    Don’t do it!

    Posted by MK Evans on Aug 30th 2021

    Look I bought a LDAG and thought I could hold out. I tried other covers but they just didn’t have…. THE LOOK. They didn’t have the look, the feel and epic ness of the railscales, so I had to get two. Now I need to get some for my other rifles. DONT DO IT! It’s a trap! They will have you addicted!!!

    4 and 3 slot honeycomb XOS MLOK

    The grip is undeniably amazing. The texture is just enough grip so it's not too aggressive. Then we come to how it looks...BADASS! The only down is the price, but the product itself is the best in the business. Therefore buy once, cry once. Buy them, you won't be disappointed.

    Quality Product

    Posted by Mike on Aug 8th 2021

    Great product but they are a little on the pricey side. The fitment is great and the grip/protection they provide is awesome. They are also very aesthetically pleasing. I would definitely recommend if you don't mind spending the extra money.
