    Superior quality I’ve used other products including magpul and rail scales quality of the hardware included is second to none. The screws don’t get stripped out and the length of the screws doesn’t protrude so far that it scratches or rubs on the barrel or gas block etc. this is my third purchase from rail scales and they won’t let you down.

    XOS-H honeycomb

    The Karve and H setup is very smooth. I put this on my primary setup and am satisfied. Ordering more for my other rifles. I’ve gotta try the dragon scales next.

    Expensive, but great product

    Posted by Michael on Jan 28th 2021

    I bought this after reading about them. Never heard of railscales before. So overall, its very sturdy and well made. Its made of a patented material of theirs which looks and feels like some type of fiberglass/plastic material. I got the matrix design and its an aggressive pattern. A little rough on bare hands, perfect when using gloves. Only downside is cost. Maybe cut out the super fancy box it comes in or find some other way to bring down the price to make more people interested.

    Works seamlessly with the Karve-P, and turns your ordinary weapon in pure perfection.

    Nothing compares!

    Posted by Phil on Oct 6th 2020

    Never used any type of grip scales before but I switched hand guards and still needed more. The Aero Atlas S-One with this scale along with the Karve-P is an excellent combination. Grip for days!

    Great product, great service!

    Posted by Kevin Pavlich on Jul 24th 2020

    This is a great product! Lightweight and has great texture for non-slip grip. I first ordered the 3-slot and after putting on my rifle, I realized it was too small for my monster hands! I reached out to Jake at Railscales and he informed me how to make an easy exchange for the 4-slot. Great service, very easy to work with, and products are of good quality! I will pay for this quality all day long! I will be coming back for all my future needs!
