    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.

    Nothing compares!

    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!

    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!

    I have one of these on my AR it’s a very cool design. No one else has anything quite like it. It gives the rifle a Streamline look and providing good grip and heat protection. I’d 100% recommend, great addition to any firearm.
