5 Karve P
Posted by Chris on Sep 18th 2019
Smaller than I thought it would be, but it’s not a bad thing! Was very easy to install and attached very solid no movement at all after going to the range. For me allowed perfect placement for a C grip on the hand guard. Only problem is now I want some railscales to match!

5 It's my firearm that look and feeling
Posted by Jovaughn Scott on Sep 17th 2019
I love light weight feeling with solid strength the rail covers are designed to look good and non slip I have purchased a karve p for my scorpion micro because the magpul was awkward looking but the karve was exactly what I wanted comfortable and minimal rail space I actually brought another one for future projects .. if you want a finishing touch pick any product for the win

5 Great foregrip alternative
Posted by David Walters on Sep 17th 2019
Small, sturdy, definitely does its job. Anyone looking for an alternative to a larger VG, would highly recommend. Can't speak to the metal version, but the polymer seems more than sturdy enough.

5 Genius Design
Posted by Michael on Sep 17th 2019
This little thing FAR exceeded my expectations. Every curve was designed to fit your hand perfectly without any sharp edges. Also angled just enough to be able to pull the rifle into your shoulder very nicely. I will be using this quite a bit going forward! Thank you so much railscales!

5 Minimalistic and Lightweight

Great fit and finish. I ordered the polymer one so there would be less of a chance to scratch my rail. Excellent!

5 Minimalist, light, compact
Posted by Anjel Munoz on Sep 17th 2019
I, like many others, care a lot about the looks of my rifle. I care about how one thing has to be in line with the rest; like many care about the lumens their light has or how sharp their knife can be. Some do not care and probably put their shoes on before they put their socks on. Everyone is different. But I will tell you that this hand stop is ergonomic and I cannot find the same satisfaction in any other since I placed my eyes on this. I saw a post on Instagram, refreshed my feed before I could see it and it was gone... But I found it. Later than I wished but I found it. I cannot be more happy with it. Love it and it looks great. For example, I had an SI hand stop on mine; loved it and continue to support their accessories on my gear; local to me means I will support. But no one can make the quality hand stop Rail Scales has. I will not go back. If it breaks for a dumb reason (I have seen it handle and heard great reviews) then I will buy another and another and another. Great purchase.

5 Can't go wrong with this one!
Posted by Sam F. on Sep 17th 2019
I couldn't justify dropping the money on the aluminum one, but this thing is outstanding for the price. Railscales stuff doesn't have to come with a big price tag!
