    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.

    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

    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

    Posted by RidgeTac on Jun 22nd 2021

    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.

    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.

    Posted by Moe on May 31st 2021

    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!

    Posted by Osvaldo on Apr 28th 2021

    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.
