    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.

    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!

    Karve aluminum

    Posted by Anthony Quintero on Mar 23rd 2022

    I wanted a minimalist option that was lightweight and functional. Something with the reliability and dexterity to grip firmly and adjust positions smoothly. This product does all of that. I would highly recommend as a must on any new build or prebuilt rifles.

    Precise made piece that fits exact. I run mine on the left side of rail as a hand stop between thumb and index finger. Then thumb over rail. It adds to the support of the platform and not just "another thing to have". Weight is nothing for those of you trying to build light. Run it on the side with the front lower RSB GRIP. you’ll never go back.

    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.
