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 Handstop is Pretty Darn Good

    Have the Karve handstop on my 9in AR, it works fine for now until I form 1 my gun. Awesome product so far!

    Karve aluminum

    I wanted a minimalist option that was lightweight and functional. Something with the reliability and dexterity to grip firmly and adjust positions smoothly. This product does all of that. I would highly recommend as a must on any new build or prebuilt rifles.

    Karve

    Precise made piece that fits exact. I run mine on the left side of rail as a hand stop between thumb and index finger. Then thumb over rail. It adds to the support of the platform and not just "another thing to have". Weight is nothing for those of you trying to build light. Run it on the side with the front lower RSB GRIP. you’ll never go back.

    Best I’ve seen!

    The Karve lives on my MPX K. Very high quality with nice subtle aesthetics. Very easy to install on M-LOK. If you are looking for a hand stop, look no further.

    Perfect size. Pictures make it look more harsh then it actually is.

    Karve-P

    Posted by Ken N on Oct 2nd 2021

    One can’t really appreciate how unobtrusive the Karve is until you see it in your hands. This was exactly what I was looking for in a handstop. Just enough surface for good reference and purchase. Love how light it is. The finish is top notch. So far, very happy with it. Would have expected nothing less from Railscales.

    Functional Flair

    Posted by Clean Cal on Aug 18th 2021

    In similar stride with my Anchor review, if you're uncomfortable with the price point, there are other options on the market but understand you get what you pay for. The Karve, like the Anchor is in my opinion the absolute best in machining, texturing, quality and functionality. The Karve works flawlessly on my 7.5 inch build. I highly recommend this product.

    Stalwart Item

    I do a lot of shooting gloved up and this allows for a deepened hand posture while still being rigid enough to bite the glove as I pull rearward. Superb machining and quality hardware. I have zero complaints. It does the job so I can keep-it moving.
