5 Karve-P
Posted by Chip on May 5th 2021
Well made, lightweight and easy to install into the XOS-H railscale. My hand indexes quickly to it and it feels rock solid. The fit and finish is excellent, no burrs or sharp edges. It’s low profile and haven’t had any issues with it snagging on clothing or gear, and it takes a beating. Buy and install with ease and confidence.

5 Great Stop!
Posted by Anthony Hunsicker on May 4th 2021
Very tactile and easy to locate, light construction, and ODG. Whats not to like?

4 Like it a lot, but...
Posted by Chris Smith on May 3rd 2021
I think it's a great hand stop. But, a little overpriced for what it is. Would have purchased the aluminum version, but is also overpriced at $79.00. That being said, I have multiples of these and use them frequently. No durability or performance issues. I'm pretty hard on my firearms and shoot competitively weekly. A $49.00 price tag on the aluminum version would get 5 stars all day.

Great hand stop. No different in comfortability than metal carve, however not a robust.

Definitely a must have. Keeps rifle stationary when shooting and minimizes recoil.

5 Karve P
Posted by Matthew Gabbard on May 3rd 2021
90% of my rifles have the Karve P on them, the aluminum version is great but at a fraction of the price it does the same thing. I’ve never purchased the aluminum Karve so I can’t speak to it vs. the Karve P, however the P fitment, size, feel, etc. Everything is spot on for my needs

I’ve tried several VFG‘s and hand stops and this is by far my favorite. I have them on all of my AR’s now.

5 Karve-P
Posted by Kevin on Apr 21st 2021
I mounted this on an S&W M&P 15-22 in FDE and color match was very good, understanding different manufacturer's FDE pigment and quality control can vary, this is very nice. At package opening it was well protected, a sticker, a personal thank you from the owners (an appreciated nice touch) and it came with the Karve-P, Allen wrench, M-Lok, and countersunk Allen screw with Loctite applied. I thought this was going to be too small, but after considering the value of “small” equating to weight, i liked it that much more. Mounting was very simple and incredibly comfortable after a few position changes to meet my preferred hand position.. The unit itself is rugged and M-Lok fitment is snug. I am not a fan of poor workmanship and this is NOT an example. I’m looking forward to range day so I can get the true impact of its utility. Nice job ladies and gents, keep up the great work.
