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.

    Machining is flawless, fit and finish is perfect. I do think I'll try the larger one for the next project

    I really wanted one of these for awhile. Spent a lot of time trying to figure out how i wanted it arranged with the other peices I was going to get. Very happy with the outcome and would definitely recommend to anyone looking for some quality AR parts!

    Love the look and feel of this thing. A little smaller than I expected but it works perfectly for my needs and you can really feel the quality in it.

    Great feel, fit and finish. Great packaging and easy installation with clear instructions. Will likely use on future builds.

    I like it

    Posted by Ryan on Aug 25th 2024

    I like this product but the price point could be better, however this stop is aluminum. Many others are made of plastics. The pattern is nice, it’s well built. I do wish it was slightly larger, it’s rather small but it doesn’t change its effectiveness. This one was purchased for a lever action. It’s out of the way if I want to be more casual and acts to effectively secure my support arm while cycling. I would buy it again.
