5 Karve-P
Posted by Joseph Smith on Jan 23rd 2023
I like that it takes 1 space in M-lok with a small profile, it just sits perfect and flush. 10 out 10 will recommend!

5 Superior

Lightweight, durable, and sleek. Good size to put in between fingers instead of just a hand stop at the pinky. Love it

5 Nice
Posted by Dude on Dec 25th 2022
I got the polymer version because the aluminum one wasn’t available. Not sorry. I like it. I have this in combination with a 2 slot piece and an arisaka finger stop in front. 3 slot scales on the sides. Works perfect for me.

Exactly what I wanted, I couldn’t be happier. It’s small, light but sturdy. It helps to keep my rail profile minimal. Their customer service is truly awesome too, order with confidence!

The grip is Perfect for my 8” 300blk. Only had minimal space to place and only needed 1 pic rail slot. Received Shipped notification 30min after purchasing. Arrived 2 days later. Very happy with product.
