Product Overview

Now shipping with our new custom Torx T20 fastener!

Karve® Hand Stop - Offering a wide range of functionality, our patented Karve Bi-Directional Stop is our most popular forward hand control product. Machined out of 6061 billet aluminum, and available in 2 anodized finishes with a Type 03 Hardcoat anodizing. The Karve is a compact and ultralight solution for multiple shooting styles and is reversible to accommodate a “push” or “pull” style grip. Compatible with modern M-LOK rail systems, it only takes up 1 M-LOK slot, which will allow it to fit inside the cutout of our XOS-H Scales, available in both Machined G10 and High Temp Polymer, making the Karve one of the most versatile solutions on the market.

This will be the final run of the Karve to include the COG multi-mount piece with Keymod compatibility.

    Karve

    Posted by Benjamin Londrillo on Sep 30th 2019

    Was looking for something that not only worked great, but integrated seamlessly with my rail. I really didn't want something so large that it took away from the aesthetic of my custom build, but without sacrificing a functioning firm grip. The Karve was exactly what I was looking for. It offers great ergonomics, aesthetics, practicality and usability without drawing too much attention to itself. Super lightweight, durable, and just plain sexy. Shipping was fast and installation was easy.

    Great minimalist hand stop!

    Posted by Evan on Sep 21st 2019

    I ordered a Karve to go along with and XOS-H. Seamlessly integrated rock solid piece of hardware. I have seen people comment about the prices of the products. Save up your money and purchase. You wont be disappointed in the products or customer service.

    Best hand stop ever

    Posted by Robert on Sep 17th 2019

    I’ve tried almost every hand stop out there in this is by far my favorite. I have one on every AR I own.

    Perfect fit

    Posted by Edward F. on Sep 17th 2019

    I have tried out a number of hand stop style grips out there, and this thing fits my hand perfectly. Not too aggressive, plus it's small and light. Great product!

    Top notch in every way

    Posted by Allen on Sep 17th 2019

    Everything about my experience with Railscales was outstanding. Their website is fresh, the checkout process is fast, their customer service when I reached out with a question was amazing (Thanks Jake!), their ship times are quick, and their packaging and products are self evident of a product that has a lot of time and energy put into it. Couldn't be happier with my purchase and will definitely be getting more from them in the future!

    More than I usually pay, but well worth it

    Posted by Tom M. on Sep 17th 2019

    I tried to build a rifle on a budget, but after having numerous people recommend this to me I had to try one out. Couldn't be happier. Might have to eventually pick up some scales to match.

    Nothing else like it!

    Posted by Jared K. on Sep 17th 2019

    I have tried a lot of different styles of handstop, and there is just nothing that compares to this low profile design. Really cool product.
