G10 XOS™ in MLOK

(104 reviews) Write a Review

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 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. 

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.

    Dragon Scales

    Posted by Ash on Feb 1st 2023

    These are hands down, the best grips on the market. Pick a category, really. Heat Gripping Looks.......C'mon, they're Dragon Scales. What's more badass than Dragon Scales? Nothing, that's what! If one of the other designs catch your eye, get them. You won't be mad about it.

    G10 XOS in Mlok

    Posted by Aldo on Dec 8th 2022

    These are awesome! They're pricier than standard mlok rail covers but they're more than worth it. They're the only rail covers I get. I have them on the 3, 6, and 9 o-clock positions on all my AR's and my wife likes them on hers too since they don't add much width to the rail. I have both piston and DI systems and they do a great job at keeping the heat off your hands in both. If you're considering getting these I highly encourage it. 10/10 would recommend.

    I would have dropped the rating a star for the price/cost but the quality, material, and precision manufacturing easily gets an extra few stars. I went with a four-slot XOS-H rail on the bottom with the Karve, and then two three slot XOS rails at the 3 & 9 o-clock and that gave me the perfect coverage that I wanted. Not thrilled with the price but I would certainly do it again simply for the quality and precision of the product and solid feel and texture they provide.

    I run these on several guns, in all the grip patterns. The only choice for mlok panels.

    Grip like a dragon

    Posted by Soycery on Oct 31st 2022

    Popped theses b-boys on with ease! Cop’d the Dragon scale version and they feel great. Rails still get hot af but they def mitigate that heat well all things considering. I’ll be back for more and shared my experience with the homies. They dug em as well and have already stopped by to scoop a set of their own! Great job on these, cheers!

    Quicker movements achieved

    Posted by Sean Laurie on Oct 13th 2022

    I felt a little crazy at first spending this much on grips. I mounted these and immediately changed my thoughts. And these do help heat after 2 mags.
