Posted by Steven T Robinette on Feb 2nd 2021
I really like the shape of this one over all the others that I have owned. The angle & curvature are just the right amount for me. I also love the grip texture on both sides. So I can get a good solid grip even whether I decide to place a finger in the front or the back of it. Most of the competition didn't even consider that. Great product.

5 Great product
Posted by Michael on Jan 28th 2021
I bought this after reading about them. Never heard of railscales before. So overall, its very sturdy and well made. Large enough to really stop my hand from sliding back. Fits my midwest G4M mlok rail perfectly.

I run a couple g10 Karves and a few Karve-Ps on all my rifles as well as scales. After much searching they are my favorite and I found them very comfortable as well as providing great control. Only product I will run now.
