    This is the best minimalist handstop on the market and I've gone through a bunch of them.

    Billet Karve

    Posted by Joe on Apr 25th 2020

    This is the best attachment I’ve used yet. It’s great for mounting barriers and doing close quarters work. The extra contact point helps in multiple/awkward shooting positions. It’s low profile so it’s much easier to work around obstacles while affording you the option to rest your barrel on cover. It’s great tool to have on my weapon.

    This thing is phenomenal, both in appearance and quality. A small footprint, for a huge added benefit. Greatly improves shooting experience

    Railscales Karve!

    A little on the pricey side, but man! It's sturdy, super light and feels and looks so good. It doesn't add any bulk or weight to your rig. It's also very versatile and can be used as a stop against a wall or standing objects to make those critical shots. I recommend the Karve to anyone.

    Simple, yet simply the best.

    I ordered a bronze Karve, along with 2 XOS, and 1 XOS-H scales for my Sig Sauer Canebrake. I dropped a review of the scales on the XOS-H page, for more on the scales. As for the Karve, it's my personal favorite handstop that I've used. Previously that title belonged to the B5 handstop (I've got a shorty one on my Scar 17). The Karve beats it imo, due to it's overall lower profile, minimal single slot mounting, ability to integrate seamlessly into the XOS-H system or inline with other Railscales, comes with hardware for both mlok & keymod, it's reversible (adding to it's versatility), and of course imo very superior in aesthetic design as well. I have mine installed inverted, about 3/4 forward on the 6 o'clock rail. This makes for a forward handstop on my short weapon, while also providing a positive contact point that I can wrap a finger/portion of my hand on and get a snug tension against my shoulder. This configuration also allows me to use the forward stop as something to push against, while firing with my brace folded, providing positive tension on my sling, thus stability! Furthermore it provides a forward stop to push into barriers.
    Lastly: the setup just looks and performs badass! If you're hesitant, like I was, just do it! You wont regret it. I dont usually go out of my way to write reviews. I did for my Railscale products simply because I know I was unsure before ordering, and all doubts were blown away. Cant wait to order more Railscale products for my collection!

    I got my Karve in last week and just got back from my first trip to the range with it today. Let me first say the quality and craftsmanship of the product is above all my expectations !! It is well built and performs at a very high level. I was able to run a variety of drills and at every level this is a quality product. The customer service that I have received has also been perfect. I can’t recommend Railscales and their products highly enough !!
