Product Overview

RSB® Vertical Grip - A fully machined ultralight stubby aluminum grip. Designed for PDW and shorter barrel setups but its ergonomics also find itself at home on carbines as well.

When used as a broom handle style grip, the RSB® allows for a 3 fingered grip with the pinky over hanging the bottom. XOS-H® scale compatible.

    Wanted to try the RSB since my experiences with foregrips were only with plastic pieces. This is such a high-quality, well-built metal piece. The grooves are very ergonomic for my fingers. Additionally, it doesn't weigh much more than the traditional polymer versions. Lastly, it comes in this neat little toilet paper tube looking thing which I thought was very clever. Well done Railscales!

    Smooth and clean. About 4 fingers long. Not to big not to small. Great for control.

    Can’t lie RailScales is a bit pricey but so far I’ve had nothing but good things to say about their products. The RSB is the perfect size for the use of my Geissele duty rifle. Fits perfectly in the XOS-H and is just big enough for 3 finger grab. Once again RailScales hasn’t disappointed and will continue to purchase in the future. 5 out of 5 hands down.

    Machining is perfect and it’s very light weight. Got this paired with the Parker mountain rep-lok rail on my scar and it looks extremely clean. Especially with the the other 50 shades of FDE

    Fits a certain niche perfectly.

    Stubby vertical grips have long been a thing in the carbine world. While hand stops and more inventive grips (Karve and Anchor/LDAG) offer serious ergonomic value, the control that you get from the RSB is unmatched. Ergonomics are similar to (but better than) legacy Tango Down stubby grips, and perfect for the thumb brake grip style that many of us have been using for years. I was skeptical of one grip working with Keyword and M-Lok, but the system is super simple, precision machined, and completely genius. Fit and finish is abnormally perfect. If you're looking for a stubby vertical grip to use with that shooting style that many of us have used for years, this is a great option for it. Absolutely awesome piece of equipment.

    I am so glad that I was asked to rate product and company. I own a company as well and I appreciate the opportunity. First, your company is fantastic! Ever thing about it, I mean the entire transaction start to finish was flawless. And you know you are dealing with the quality company when it comes to the little things like the shipping package. My RSB arrived in a small tube with everything that it should have packaged neatly and had a top that you can put back on if you are not going to install immediately. That may sound dumb and insignificant but it actually is a huge plus. Again attention to the small things.As for the product itself, there is not a better one on the market. Not only is it extremely innovative and user-friendly as it can be installed on multiple mounting systems and the hardware to do that is included, it is perfect in every way. It really puts all the other ones I have purchased, and I have purchased a lot of them, to shame and I will be ordering several more. So my experience has been to receive a first class product from the first class company! You folks got it right all the way around!
