    G10 xos in mlok

    Posted by Rhett on Jun 16th 2021

    These scales are amazing. My only discrepancy is that there needs to be a 2 slot option for the Honey badger. 3 slot wont fit the bottom of the hand guard. Thusly, I ordered karve anchor and a single slot as well

    Grips that Grip

    Posted by Dustin on Jun 1st 2021

    These grips do exactly what they advertise. But the build quality and quality control set them apart from the competition.

    G10 XOS MLOK

    Posted by Chip on May 5th 2021

    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.

    Pricey, but worth it. Great texture to grip

    Posted by Jordan Gibb on Apr 26th 2021

    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.

    G10 XOS (Honeycomb-4 Slot)

    Posted by Liam on Apr 14th 2021

    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.

    Whoops they did it again..

    Posted by Tyebo on Apr 5th 2021

    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!
