    Works on URX

    Can confirm works on URX 4 MLOK on my SR15. Swapped my Magpul MLOK covers for these. Night and day difference.

    RailScales are the highest quality rail covers bar none you can feel the quality of material used when you hold it they help grip and are aesthetically pleasing they’re worth every penny and I’m happy to be spending money with a local company just a few hours away in Claremore OK. Keep up the great work guys can’t wait to place another order!

    G10 xos in mlok matrix

    Posted by Jason s on Feb 23rd 2021

    Amazing absolutely love the quality and fit . My only complaint is that the don’t make the xos in a smaller mlok pattern like 2 or 2.5 slot I think it would offer more options on pistol builds

    Excellent grip, with or without gloves, rain or shine. Excellent product from excellent company. I was recently informed the XOS-H will accommodate both the Karve and the Anchor if you want to switch the two out depending on application.

    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. Fits my midwest G4M mlok rail perfectly.

    Was a bit nerves to order the XOS and XOS-H for my Armalite AR10A after not seeing it on the compatibility list. Decided to go out on a limb and order and I’ve got to say they fit perfectly on the Armalite M-LOK rail. Best grips I’ve ever put on a rifle and will definitely be ordering from you all in the future. Great product!

    4 slot matrix m lok

    Posted by Dylan on Nov 18th 2020

    They fit very very well on my bcm rail, look great. The matrix design is fairly aggressive so that’s something to be aware of with this pattern. I like it, it gives a really solid grip. I can not say how they hold up to eat and abuse since I have only put them on the rifle and haven’t been able to test there durability or how well they keep heat away from your hands but they cover the rail all the way around if the you get three rail covers for each side of open rail. Price is a little much but they seem to be worth the money and very well made.
