5 Exactly what I wanted!
Posted by Trent on Dec 23rd 2020
I did PLENTY of research on hand stops before making my decision to go with the Karve-P. The price difference compared to the Karve definitely swayed my decision towards the polymer option as I do not mind polymer. The product arrived in excellent packaging and even included a Gratitude note, thanking me as a customer that was hand-signed. You don't see that a lot nowadays. I will 100% be a repeat customer and will recommend Rail Scales to family and friends!

Simple, light, great ergonomics, and does the job. I'm switching all my AR's over to this one.

5 Only handstop I use, seriously.
Posted by Noah Carlson on Dec 4th 2020
I have two of these and plan on getting more. They will probably phase out all other grips and handstops I use, until I try out the Anchor and RSB at least!
