5 Pairs perfectly with the XOS-H
Posted by Adrian G on Mar 8th 2020
Finally got around to running the Karve P paired with a XOS-H on my carbine this weekend at class. Here in Michigan during March it’s very cold wet and muddy. Needless to say the scales facilitated control of the gun by a long shot. By the end of the day my gun and I were covered in mud but I was still able to manipulate the weapon due to them. Others in the class were struggling with a slick rain. Hands down one of the best investments I’ve made. And I’ll definitely buy them again for my next build.

4 Karve-P hand stop
Posted by Justintime2 on Mar 5th 2020
Karve-P hand-stop is a nice piece but I wish they’d offer it in the G10 to match the RailScales. Grey is a little too light to match the RailScales (although they do apparently lighten up with age) and the black to dark to match the slight grey tones. Now this is being pretty picky and it may not matter for your application but when spending a premium for parts for a nice rifle is does, at least to me. I used two 3” panels for the sides and one 2” panel for the bottom with the Karve-P behind it so they matched each others lengths overall. Their customer service is top notch, do not hesitate to do business with these guys.
