XOS™ in KeyMod

Product Overview

XOS™ in Keymod - 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 three 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

XOS in KEYMOD

Posted by Jose Moran on May 1st 2020

Wrap around rail scales work great. I ordered the 6 hole mini dot XOS in KEYMOD and installed on my DDM4 V11. They arrived before estimated arrival date, had a medical employee discount and fit like a glove. Look great, which is an additional bonus. Everything to install was provided and even had a hand signed thank you note from one of the team members. Great product. Great service highly recommended

Great Upgrade

Posted by Barton on Apr 27th 2020

Great upgrade, especially if your rail has gaps big enough to let your fingers near the barrel. The mini dot texture is great, lots of grip when you need but not sharp. The initial cost may seem high but its worth it. Will be adding to my other rifles.

Like it grew there

Posted by Jack McClane on Sep 19th 2019

I got the short Honeycomb piece for my PTR 9CT M-lok handguard. Sits perfectly behind my Arisaka finger stop and feels organic to the weapon. It’s not gonna tear up any gloves, but it’s gonna provide a good grip to pull it into my shoulder.

Best Rifle Accessory Ever

Posted by Sam W. on Sep 19th 2019

I can't begin to explain how perfect these are. I got a set of the Xos and the cutout Xos-H to pair up with a karve I already had on my rifle. The minidot doesn't look like it would lock in as well as it does, I got it for the look and was pleasantly surprised how well it grips. I am saving up to put these on every rifle I have. Great stuff Railscales.

Minidot is fire!

Posted by Jess on Sep 19th 2019

If you don’t have the xos in minidot then you’re support hand hasn’t lived. The new xos is amazing at heat protection and the minidot texture is some kind of witchcraft creating the nest combination of not too aggressive and grippyness. Looking at it I would never have imagined how grippy it is. Ordering a second set of xos for my other rifle.
We need an anchor with minidot!

THE BEST

Posted by Shawn on Sep 19th 2019

After trying all of the scales available on the market including the original Railscales, these are without a doubt the best on the market. They have over double the surface area of standard scales and look awesome. The Honeycomb texture is aggressive but not uncomfortable to shoot. Even though they cost a little more than comparable products they perform at a much higher level. Keep up the awesome work guys.
