Product Overview

Now shipping with our new custom Torx T20 fasteners!

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. Compatible with modern M-LOK rail systems, it only takes up 1 M-LOK slot, which will allow it to fit inside the cutout of our XOS-H Scales, available in both Machined G10 and High Temp Polymer.

    The RSB is lightweight and sturdy. Everything from Railscales is top notch. My go to for all their accessories for my rifles.

    Quality

    Posted by Rex on May 9th 2022

    Big fan of the quality and ability to apply to both Keymod and mlok. Solid build. The price tag is the only downside.

    RSB vertical grip

    Posted by Jake on Apr 16th 2022

    I love this grip! Super light but stout. I use my vertical grip to pull the weapon back towards my shoulder with my middle and ring finger, while wrapping my thumb around the rail, so this grip is prefect size for that. If you use your grip like a handle, your bottom two fingers will hang off (unless you have tiny hands). Quality and customer service with Railscales is superb. Fast shipping too. I will buy more from these guys. This is my second RSB. I have one Terra bronze and one black. I love them.

    RSB Vertical Foregrip

    Easy to install, sturdy, lightweight, and comfortable. Provides enough grip surface without being overly long.

    Outstanding!

    Posted by Nyel Aquino on Nov 8th 2021

    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!

    Clean

    Posted by John Cornell on Sep 9th 2021

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