Looks great, doesn’t feel cheap. Awesome guys at rail scales that called to make sure I had the colors right because I had two different colors in cart.

3 Karve-P Sent with to small of a bolt
Posted by Kyle kidder on May 4th 2020
The bolt that was sent with my handstop was too short and couldnt even screw on the mlock nut. I had to use an bolt and nut from a previous handstop. Other than that its a very nice product.

Really love this product. Small, Simple, and Strong. I'd give it 5 stars but they make a machined version

5 Karve-P
Posted by Chris on Apr 27th 2020
Overall, I am very impressed with the Karve. It's extremely light due to its polymer construction but very sturdy. Despite it's size, it does a great job performing as a hand stop without taking up a lot of real estate on the rail. My only regret is not pairing it with the Rail Scales that have the cutouts for the Karve. Fantastic product that fits well in the hand and on the weapon system.
