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.

    Precision

    Posted by EZ on Nov 25th 2022

    I would have dropped the rating a star for the price/cost but the quality, material, and precision manufacturing easily gets an extra few stars. The fitment with XOS-H rail and how solid everything feels remarkable.

    Awesome product

    The Karve is the best forward control piece on the market. It’s slim enough to not get snagged and provides the perfect about of stabilization and indexing. Very happy with this product.

    Karve

    RailScale’s billet aluminum Karve is a functional addition to any modern rifle. Its ingenious cog mounting system allows either M-LOK & KeyMod installs. Flawless fit with any XOS-H, PMM REP-LOK lower rail, or M-LOK handguard . Excellent stability control & barricade stop. I would recommend for any rifle upgrade.

    Less is more

    Posted by Jonny Kirkland on Jun 11th 2022

    This hand stop/grip/ finger groove is simply the best. I prefer a clamping grip, I have found that most stops are still too present. This gives me the grip I like and does not interfere with the feel of the hand guard itself.

    Drive It!

    Posted by Christopher Lynch on Apr 23rd 2022

    It is the smallest and lightest but most solid handstop I've ever seen.. I've seen a fair amount of weapons come with handstops and stops, the shock wave and the scorpion come to mind.. This is simply a rugged and quality but extremely light weight option that lets you reverse it if you want. You have to have a C grip or similar grip to really take advantage of it pulling backwards But it's versatile enough to run facing forward or backwards. I opted for this over a stubby broomhandle like the Anchor and am happy with it.

    Karve

    Posted by Dalton on Mar 27th 2022

    I have always ran a vertical grip on my rifles over 13”. I was on railscales looking for a completely different product when I came across the Karve. Within days the Karve arrived and like everyone else I put it on my DDM4V7 that day. The next day I took it the range and was instantly happy with the purchase. I was able to get up on sights extremely quick and I found that I was a good bit more accurate when firing from a standing position. The feeling of this stop is next level, I highly recommend to anyone that is on the fence wether or not to purchase this to DO it!
