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.

    The Best Out There

    Posted by Caleb Mattern on Jun 8th 2021

    It’s amazing to me how a small piece of kit like this really helped me manage a nose heavy rifle (yeah, bro I lift). So I get the rail, the light and hot button all linked and start shaving weight (mounts,pins, rear irons etc). Surprise ,surprise the the thing was way off balance. This little piece of well designed aluminum gave enough rearward tension and added support that the rifle is no longer a P.I.T.A. to work with. It made a remarkable difference without making the problem worse (weight wise).

    Best in market.

    This is my second unit for AR pistols. Also have the anchor for one of my SBR’s and I don’t know how many G10 railscale I found this company in search of some quality grip scales & now I come back for whatever they make as they are second to none. Buy with confidence! You can’t go wrong.... but do check out the entire site there’s many thing you might want o get to complete the package.

    Great quality!

    So far I’m in pressing with the quality of the Karve. I was debating between the Karve-P and this one and I’m glad I chose the Karve. It’s a bit more expensive than what I would pay, but the quality of machining made up for it.

    This product is perfect and well made . I purchased this for my Q honey badger. Would recommend this to anyone that likes a low-profile grip

    beaut

    machined beautifully. One side has a more texturized feeling for barricade support or you ran run it the other way and have it as a hand stop that doesn't cut into your hands!

    Very solid

    Posted by Jordan Gibb on Apr 5th 2021

    Great product, the aluminum is very strong. I've got a small box full of various grips, but this one is one of my go-to's when I get ready for the range. The jaggedness being built from aluminum gives it an extra "grippiness" that you just can't get from polymer, period.

    New Customer... now a life long customer

    Posted by Nav on Apr 3rd 2021

    I’ve tried just about every rail covers/panels in the market, but stayed away from railscales due to the price. I finally decided to pull the trigger, and just received my first order yesterday (a couple days after placing the order). I eagerly unboxed, and was immediately impressed by the quality, fit and finish... plus the bad a$$ sticker swag. I selected my SR-15 14.5” MLOK upper as the host to the Honeycomb G10 scales, and it was love at first sight. The grip is perfectly designed with an amazing feel (not too aggressive, yet significant grip), the look is off the charts cool (sexy af), and it’s a perfect marriage for my Knights upper. I also added the Karve, which is my new go to handstop... love the fact that it works for MLOK and Keymod. Such a simple feature, but a huge value and convenience. Thank you rail scales for making a phenomenal product. You truly get what you pay for, and you have a new customer for life. I intend to upgrade all my uppers to rock the scales! Looking forward to try a couple other patterns as stocks replenish. Thanks again! - Nav
