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.

    Perfect

    Posted by Mark C on Mar 29th 2021

    Bought two of them. Need a couple more. Can’t recommend them enough. Actually just recommended them to a coworker who’s building a 300 Blackout. Shipping was quick too!

    Karve

    Light, sturdy and compact. I ordered this because it does not take up much space and provides the leverage I need for my support hand. It is the right size for my hand and is not very abrasive.

    Exactly as advertised.

    Amazing stop, lightweight, and durable. Looking forward to beating the snot out of it during drills. Worth the money in my opinion. Running it on a Gissele 14.5.

    Karve

    Quick shipping and quality of product is perfect. Easy installation. Would def recommend blue thread lock just to make sure Karve stays put. Very comfortable at 6:00 position, low profile, quality of manufacturing is impeccable. A must buy in my opinion.

    I've purchased a Karve, Karve-P and 2 Anchors. None have disappointed. Craftsmanship is excellent!
