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.

    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.

    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.

    Best small VFG on the market

    Posted by Chris Patire on Feb 16th 2020

    I love this little VFG it is very lightweight and sturdy. It looks badass on my AR rifles. Better construction and durability than the plastic competitors. If you are looking for a forward grip look no further, just order it.

    You need this!

    I don’t like the way vertical foregrips look. Are usually run with hand stops but then I saw this RSB on Instagram. Had to have it! No regrets! The craftsmanship is amazing and it is super lightweight. Very comfortable as well. I wish I could show you guys a picture but if you are on the fence about this, just get one! You won’t be disappointed!
