5 KARVE-P Hand Stop
Posted by EDF on May 3rd 2023
Great product, not to small not to big. Light weight that you can’t tell they have been added to my carbine. Will purchase again when needed.

Perfect size for shorter rails. Gives you just enough to C-clamp and pull back for best control. Highly recommend.

5 Carve-P
Posted by Andrew on Mar 9th 2023
Can’t go wrong with anything Railscales. This does the job. Add it with their G10 XOS-H and it’s a killer combination. Polymer is solid! I can’t imagine the metal one being that much different. Added to my mcx as their handguard is bulky and wanted something minimalist and this is perfect. Texture is there, style is great. Can’t go wrong with it. Would I buy it again? Definitely! Other than that being useful for your rifle get to training.

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
