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.

    Really cool little product here. I have a number of RS stuff and they just have a knack for great design and function. Highly recommend.

    Couldn't wait for this thing to come in, I was never in love with the Anchor design but Railscales knocked this one out of the park! Kudos guys!

    RSB

    Posted by BG on Aug 24th 2019

    I was looking for a shorty M-Lok vertical grip. I personally find verticals grips more advantageous for muzzle strikes and controlling the firearm in situations where fine motor skills start to deteriorate. The RSB is one of many verticals grips on the market however none offer the modularity, high quality machining/anodizing, and solid mounting system that the RSB comes with. Even the packaging is something to admire. This grip is best paired with the G10 railscales. I’m loving the setup on my work rifle, a 11.5in SR15 SBR.
