XOS-H™ in MLOK

Fits the Foxtrot Mike Products FM9 perfectly.

I have these on several MLOK hand guards on the 6 o clock position with the original scales at 3 and 9. The XOS-H allows for more grip and fits the rounding of your hand at 6 o clock with its extra siding. Rock solid mounting and G10 strength, there is no better alternative (or better looking), with great grip texture. I use both the Karve and RSB which fit snugly into the slot, tight tolerances, and seamless low profile. Highly recommend either of those, Karve as a hand stop for c-grip and the RSB allows a variety of grip styles including c-grip, as a hand stop, one or two or three fingers on the stubby, etc. Not long enough for a true broom stick grasp though you can still pull it off if you desire. Both are very durable for use as a barrier stop as well.

Seamless integration with the Karve I ordered as well. Just what my rifle needed for a extremely lightweight durable gripping surface.

I really like how they designed this around their other products, would just like to see a few more options to fit in them!

Can't say enough about how cool and customizable this is. Really hope they add some more stuff to the Xos H lineup soon!

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!

I purchased some HTP Scales, XOS-H Type 1, and a Karve-P for a couple builds I had in the works. Product came quick and neatly packaged. I went to put them on the handguard to mock up where I wanted them to be after i got everything cerakoted. Unfortunately due to my own ignorance I over torqued the screws as I didn't want them vibrating off and as a result stripped a few of the heads on the screws. I shot out an email in hopes of getting a few screws sent my way and within 20 minutes I had a response telling me they looked up my order and were going to send me out a full set of replacement screws just in case, and not just the amount I asked for. Can't beat that kind of quick customer service. All free of charge too I might add! All three products are absolutely killer in form and function! I love when companies remember their customers and do everything in their power to help them out. I will for sure be buying more from them in future builds. 5/5 for the product, 10/5 for the customer service.

Railscales already had my business with the Anchor and Karve, and when I saw this show up I couldn't believe how brilliant of a design it was. I really hope they have more things coming to fit this footprint, as you can tell how much time they took to make this look and function perfectly with their other products.

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
