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

First time buyer of RS products and I’m favorably impressed. Site is intuitive and easy to use, fast shipping; excellent customer service. The XOS fits flush on the free float foregrip of my Armalite AR-19 pistol. Quality material and machining on the scale itself and included hardware, exceptionally easy to install, they include an Allen tool, nothing else needed. You can tell they take pride in their craftsmanship and it interfaces well with their other products. I bought two XOS, one XOS-H, and the Karve-P. Installation was a breeze and rock solid. The Honeycomb design esthetic looks amazing and it’s highly functional and grippy. Easy to clean, outstanding design; overall an outstanding product.
I was very skeptical when I first saw these at this price, couldn't imagine it could be worth it. I ended up getting 3 of the G10 rails in dragon just to try them out, and they're staying on the gun now. GREAT texture, and they're incredibly solid. I know I sound like a bot from the company writing this ad, but I'm actually giving some of the polymer ones to my dad for his birthday next week.
Recently purchased 3 scales in the honeycomb texture along with the Karve-P. Firstly, this is an amazing quality product. Despite the prices being what they are, when you take them out of the box and feel them, you understand why. The scales feel very sturdy in the hands and they provide you with a great grip on your rifle without being overly aggressive on bare hands. After trying both the matrix and minidot textures, the honeycomb is an excellent medium between these two when it comes to overall grip. The karve is also a great addition to the scales and gives you even more shooting stability and recoil control. I run all of these on my police patrol rifle and they are extremely efficient without adding too much weight to your setup, which is very important to me personally. Paid about $250 for all 3 plus the karve, but once you get them on your rifle, you know it was worth the investment for what they offer.
Railscales has done it again, these guys hit it out out the park with every product they offer. These hand guard grips feel good, perform great and look even better! Was a little unsure how grippy this pattern would be but they’re great whether you’re wearing gloves or not. Don’t wait, they sell out of current stock fast!
Great handguard covers, durable, heat resistant and solid. A+
This is the product is was most excited to try out. It provides a strong grip while not being to abrasive on the hand. I especially enjoy how they wrap around the rail for better ergonomics. Highly recommended!
Just picked up the 3 slot of these as a set. I love em! Very slim, very grippy however not overly abrasive in your hand, and esthetically pleasing. Went with the "Honey Comb" version.
I finally upgraded my slate black ind. grips to the XOS MATRIX and wow what a difference. The plastic SBI's were slippy. These grips are aggressive and fantastic. No slipping at all, even on my 308 AR. Would recommend if you want the best grips on the market and to pull that rifle into your shoulder to help with recoil control.
I couldn’t of been more thrilled with the look and feel of the dragon scale. I seriously can’t put my rifle down now, it feels that good. And they look down right amazing. Don’t hesitate on getting these, you will NOT regret it I promise. 11/10 they knocked it out of the park
