    I love it: great texture, solid lock up, good looking, light weight, fits carve. Only wish it was in OD.

    Awesome product and awesome shipping...

    Posted by Alex on Sep 19th 2019

    I debated whether I should invest in a RailScale setup given the costs, but after I received the XOS-H, along with the Karve-P, and two G10 long panels....I couldn't be happier with my purchase. These panels are really innovative, provide excellent grip, and weigh next to nothing. The shipping, and communication with CS was perfect. They really seem to care about your business, and pay attention to the small, yet important details in that regard. Will be doing business with RS in the future whenever it's an option. 5 stars!

    Great Product

    I already had a Karve and regular railscales, but as soon as i saw this i had to get it. Fits perfectly with the karve and makes gripping the end of the handguard more comfortable with a lot of grip. It also looks great on my PWS MK111. Keep up the good work

    Completely satisfied

    There really is no way to explain how perfectly the xos-h fit my palmetto state upper. You have to feel it to really appreciate the perfection in these pieces. I used the Karve-p with this and it really enhances the feel and control of the entire weapon. I will use Rail Scales for all future builds!

    Perfect Integration

    Posted by Chris on Sep 19th 2019

    When it comes to controls (vertical grips, hand stops) trying to set them up with rail covers of any kind can be a challenge, gaps and overlaps etc. This solves that problem, provided your using a karve or anchor. The fit is perfect and nearly seamless. I will be ordering more for my AK and 308
