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. The cylinder of the grip is offset 0.140" to allow for fine adjustment in its already small footprint by alternating its direction. When used as a broom handle style grip, the RSB® allows for a 3 fingered grip with the pinky over hanging the bottom.

    Favorite foregrip I have tried - And I have tried them all

    Posted by Calin on Oct 11th 2020

    I am one of those people who just has to try everything out. I got the Anchor first and loved it but I like this one even more. It's incredibly comfortable. I use it with honeycomb 3 slot railscales on each side and on the bottom. Super comfortable, great control and the whole system helps protect your hand.

    Better than WAP????

    Posted by The Roman Hooded Adventurer on Oct 9th 2020

    It ain't better than some WAP that's for sure but dammit, if it ain't darn near close IDK what is. I have Railscales products of some sort on all my guns and this one I just added to my SMG45. Def helps with the ergonomics. A lot of research and attention to detail went into the design imo. Or, someone was just like, hey I have an idea and then boom! This nub was born. I def would recommend to users who want something that doesn't have a huge footprint and take up too much space on the rail. Also, Railscales just makes ergonomic gear. I love their stuff.

    The RSB is my hands down favorite foreword grip, and I’ve tried many. I loved my anchor, but replaced it with an RSB recently and couldn’t be happier. The surfaces are positive and the grip is comfortable and extraordinarily light. Like boots I’ve tried tons, had some luck but now that I’ve ran with this I know what I want going forward. I have it in terra bronze and not that looking cool is key, it’s rule one, but it somehow matches my USASOC primary weapon, with its hard to match Geissele DDC pretty damn closely. Pricey but worth it, if you are a range guy or carry for work, can’t put a price on having the right kit downrange. Thanks gents-

    Im running this on an 11.5 SBR. I was using a Karve but with a DBAL and scout light the rifle is fairly heavy out front. This RSB is perfect, you can either grip it like a vertical foregrip, use 2-3 fingers like an AFG, or use it like a handstop. Machining and finish are flawless. The slight offset is a brilliant design that allows me to get my hand placement exactly where I want it for the unity taps switch.

    Awesome product. Better customer service.

    Posted by Devin on Apr 8th 2020

    Am very happy with the rsb and xos-h Rail combo. Feels great in my hand and gives that extra grip and maneuverability. Originally I got the handstop but decided it wasnt my jam and reached out to railscakes. They replied right away taking the time to answer questions about shooting styles and various grips and were able to return and replace it no problems. Very happy over all.

    My Second Purchase

    Posted by Dave on Mar 28th 2020

    It worked so well on my AR9 SBR that I put one on my AR15 as well. It's the absolute perfect length for a modified C grip and isn't long enough to get in the way while in tight spaces. Ditch that plastic garbage and go with this.
