    Has the versatility to switch between MLOK and Keymod; fits solidly wherever it's attached. Lightweight and low-profile are my jam and this thing does NOT disappoint. Thanks guys!

    Karve Handstop

    Posted by Marty Estrada on Oct 31st 2020

    Excellent handstop, fits great to a rail and locks up solid. Would definately buy again and recommend to anyone who wants a well built top tier handstop.

    I’ve tried out many hand stops to see what works best for me. This one is the winner by far. It’s lights works great for my hands, and yes it does look nice. I just wish they made the Karve for picatinny rails. Bummer they don’t. I have other rifles I’d like to get this for.

    Great handstop (and I've tried four)

    Posted by ChrisJ on Sep 25th 2020

    Great minimalist/clean design and being able to mate with the XOS-H was exactly what I was looking for! I've tried Centurion rails and four other handstops and while all were nice they were lacking in some way that I couldn't put my finger on but my voyage of self-discovery (and a post from a FCD Pond Scum member) led me to Railscales.

    Amazing quality, fit, and finish

    The quality, matching finish to my DDM and Springfield Saint, and fit are second to none. Get it. You won't be disappointed.

    Exactly what I was looking for. Low profile, grips the hand well, machined expertly. This will go on many more of my carbines going forward.

    Karve angled fore grip

    Posted by Richard S. on Aug 12th 2020

    I bought my first Karve 2 months ago and absolutely loved. It’s hard balance the product the cost initially, however once getting hands on it became apparent this is a high quality premium product. It comes pre-plumed for both M-LOCK or KeyMod with simple but precise ingenuity. The Karve fit incredibly tight, feels solid, is not cheap or feels that it would break easily. On top of making a fantastic product, after loosing a MLOCK nut I reached out to their customer service and they responded lighting fast, resolved my issue, and even were able to find more products showing sold out online. I was amazed at what a superb and easy experience with their customer service. This is a great company who makes solid products and I’m willing to bet you will see these on everyone’s rifle more and more. American made, ships from Oklahoma and arrives fast. Just buy it because these are going quick for obvious reasons
