I was like others, hesitant to splurge on a set of scales, but wow I'm very glad I pulled the trigger. I got 2 XOS & 1 XOS-H, 3 slot, scales (matrix pattern), and a bronze Karve. All products were everything I hoped for and better! High quality, plus a quick & easy install. The XOS scales PERFECTLY contour with the rail/handguard shape of my Sig Sauer Canebrake. Very low profile, and seem as if they are naturally a part of the weapon. The XOS-H scale I used on my 6o'clock rail, along with the Karve. The Karve fitment into the hole was perfect. I was slightly worried that the matrix pattern may be a bit too aggressive, however I wanted maximum grip! Very happy with the texture. It is extremely aggressive, but it isnt uncomfortable to shoot/grip without gloves. I'm very happy with the pattern/texture, as I wanted aggressive grip without discomfort, and these delivered. The Canebrake conceals most of my suppressor inside of the handguard, so it definitely gets warm. These scales made a HUGE difference in terms of heat, grip, control, and aesthetics! Cant say enough good about every product I ordered, if you're on the fence just do it!! I know I will be ordering more, asap! I'll have a Railscales setup on every compatible weapon I own.
Finally got around to running the XOS-H paired with a Karve P on my carbine this weekend at class. Here in Michigan during March it’s very cold wet and muddy. Needless to say the scales facilitated control of the gun by a long shot. By the end of the day my gun and I were covered in mud but I was still able to manipulate the weapon due to them. Others in the class were struggling with a slick rain. Hands down one of the best investments I’ve made. And I’ll definitely buy them again for my next build.
Was very satisfied with XOS-H scales and its texture. It paired seamlessly with the Anchor vert grip. I got it in Matrix pattern scales and was surprised at just how much traction they provide. The contour is perfect for the handguard on my DDM4V7.
Fits my BCM MLOK rail like a glove. Paired with a Karve, it makes an awesome combination on an AR pistol.
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!
