Product Overview

XOS-H™ in MLOK - This variation of our traditional G10 XOS™ Scales offer the same great features, but add an accessory cutout that partners seamlessly with other RailScales® products to give you multiple modular options that best fit your shooting style. While most commonly used at the 6 o’clock position with our Karve®, Karve-P®, Anchor®, or RSB™, the XOS-H™ will also fit our QDX™ Sling Mount as well as additional future RailScales® products to mount at various positions based on use. CNC machined out of high quality US made Black FR4 (commonly known as G10), our scales provide an umnatched barrier against heat transfer. They will accommodate most popular handguard rail systems, however please check the specs below to insure these will fit yours. Sold Individually

    I have used their stuff on other builds and it was quality. No different here. Awesome kit which exceeds expectations. And Jake at RailScLES has been awesome to deal with when I needed help. Will continue to buy there accessories to pimp out my builds! Bravo Zulu gents and keep that good good coming!

    G10 Xos-h

    Posted by civie Casey on May 5th 2022

    Railscales has always been one of those things I’ve seen on guns through Instagram posts and thought damn that looks sick and super grippy. I finally clicked the link and took my balls out of my wife’s purse and said fuck it, I’m buyin this set up with the karve-p and it’s gonna be badass. As soon as I got that last push of tightening to the mlok and held onto my rifle i was thrown into a Sylvester Stallone and Arnold Schwarzenegger movie, runnin through the jungle in a tropic storm clutching my SOLGW AR but my grip didn’t feel to tight because my railscales gripped my hand so much it was like glue and I couldn’t let go. Obviously I went on to run and gun my way to freedom and win whatever apocalyptic time frame movie like scenario I had been thrown into and knew…I was goin to buy railscales for every..single..gun I own..

    I was skeptical on these, but once i had them in hand wow. The grip feels really good, and there is no way your hand is going to slip even when wet

    G10 XOS H

    Posted by Anthony Quintero on Mar 23rd 2022

    I was interested in finding something lightweight and functional. I wanted something that stood out and was different from a majority of other options. I came across Railscales at GunsLA in Burbank,CA and wanted to have that on my build. I emailed with concerns on fitment for my Lantac handguard and Derek emailed me back saying that it should fit my handguard and that if it didn’t that I would be able to ship back at no cost and order another that might fit. It fit beautifully and the function and comfort are worth having on any build or rifle. I would definitely recommend because the function is as good if not better than how they look. This is perfect combo with the Karve becusse it fits flush and is very minimal on rail as part of the Railscales so there’s no need for a larger footprint on handguard.

    Worth the Money

    Posted by Alexander on Mar 3rd 2022

    Super grippy, stops heat, perfect fit on my Geissele mk14 rail. The cutout is sized for their products but my Arisaka indexer fit no problem. G10 is very durable to abrasion, will last forever and the included hardware comes with tooling and locktite for install. Aesthetic AF, worth the money.

    Paired together great with my pre-existing Karve handstop. Excellent grip with easy installation and looks great too! Helps reduce heat after longer sessions or rapid fire.

    G10 XOS-H

    Posted by Matthew Gore on Dec 22nd 2021

    I'm a long time customer with Railscales and have never gotten a product from them that I wasn't completely satisfied with. The G10 XOS-H fits nice and snug on my PWS rail around my Railscales Karve fingerstop. The Railscales feel very sturdy and secure. Railscales has once again exceeded my expectations and delivered another high quality product. Thanks Railscales!

    Best forward grip products, bar none

    Posted by Brett Koleszar on Dec 14th 2021

    I use the Vendetta Precision VP-24 Hand stop in combination with the G10 XOS-H. It's by far my favorite forward grip combo. Super fast shipping!
