5 Karve-P
Posted by MILES BRUGGMAN on Sep 28th 2020
I purchased this device for my first AR pistol build and have never used a hand stop before. So far I am very pleased with the comfort it provides with a good thumb forward shooting grip. This item is priced right and was easy to install. Good quality high temp composite that will definitely hold up to the abuse of riding around in my truck!

I own decent amount of handstops including the BCM KAG and others but I always keep coming back to this handstop. To me the Karve-P is the perfect size and has just the right curve for my hand to get a secure grip on the rail. In combination with the HTP Rail Covers 3 pack it is an affordable and ergonomic setup for control.

5 Great control device

The Karve is smaller than I thought. It has good grip and dual angles depending on mounting orientation. The molding is high quality and the hardware is good. Would prefer torx drive.

5 Krave-P
Posted by David Cato on Sep 21st 2020
I was needing a hand stop so I would not blow my fingers off because I have a 5" rail on my AR9. I looked at many of different options online. The Krave-P was just what I was looking for and needed. It was perfect for a short rail, and their sniper grey matched my Shockwave 2.0 buttstock and my Magpul moe hand grip color wise. They have an array of colors to match your weapon. The item is very ergonomical in being revirsible and only uses 1 Mlok slot or 2 KeyMod slots. You can add this to any Mlok or KeyMod rail on any slotted position (12,3,6,9). It can be used as a thumb or finger stop, fwd hand stop, or a rear hand stop, depending on how you carry your weapon. It will probably have alot to do about where u wanted it mounted. I put mine on @ the 6 o'clock position using the C‐clamp method. I could easily be put on the 3 & 9 position. Did iI mention it is made in the USA

I have these on two of my guns and like them. I have the full size on another rifle and actually prefer the smaller one as I think it is optimal size and weight. Easy install. Would buy again.
