5 Karve-P is the best
Posted by JoseR on Apr 7th 2026
This is my 3rd Karve-P. I like its ultra compact and lightweight design. Grip is very comfortable and the size doesn't sacrifice functionality. FDE color accurately matches with the color of my rifle. The addition of a torx key is always appreciated. Marker (dots) to properly align and determine correct installation is a very smart design choice in my opinion. Highly recommended!

A nice low profile stop that makes it a lot easier to pull the rifle into your shoulder. Fits perfectly in the XOS-H. Can’t beat the price of the polymer version, I wonder what, if any, benefit the ‘standard’ version offers at almost 3x the price
