    Best hand stop ever

    Posted by Robert on Sep 17th 2019

    I’ve tried almost every hand stop out there in this is by far my favorite. I have one on every AR I own.

    Perfect fit

    I have tried out a number of hand stop style grips out there, and this thing fits my hand perfectly. Not too aggressive, plus it's small and light. Great product!

    Top notch in every way

    Posted by Allen on Sep 17th 2019

    Everything about my experience with Railscales was outstanding. Their website is fresh, the checkout process is fast, their customer service when I reached out with a question was amazing (Thanks Jake!), their ship times are quick, and their packaging and products are self evident of a product that has a lot of time and energy put into it. Couldn't be happier with my purchase and will definitely be getting more from them in the future!

    More than I usually pay, but well worth it

    I tried to build a rifle on a budget, but after having numerous people recommend this to me I had to try one out. Couldn't be happier. Might have to eventually pick up some scales to match.

    Nothing else like it!

    I have tried a lot of different styles of handstop, and there is just nothing that compares to this low profile design. Really cool product.

    Love this thing!

    Posted by Marty on Sep 17th 2019

    I have used a number of different hand stops and forward grips, nothing really even compares to this. It is a slightly pricier option, but once you have one in hand you can just tell how much effort and design work went into this. Just like every other Railscales product I own, I can't speak highly enough about it.

    Incredible design and function

    Posted by Paul F. on Sep 17th 2019

    I was recommended the Karve by a friend who uses Railscales products, and figured I would check it out. It locks in perfectly with how I grip my rifle, and gives a nice low profile aesthetic. Worth every penny.
