    Function over form.... but great form too

    Posted by TPNES on Oct 14th 2019

    More durable than polymer alternatives and yet somehow lighter than the Magpul, BCM, and Tangodowns out there. Elegant lines and great looks to it, has a nice taper around the attachment point so it doesn’t look blocky on MLOK slick rails. Finger grooves work great in a variety of grips and also useful for thumb over bore C-grip styles. I’m sure it would be phenomenal on SBR and sub guns as it’s designed for but I have it on a 14.5 LPVO build and it performs great for both control and for looks.

    Good Boi

    I've tried out some vertical grips in the past and this is the first one I actually like. I placed it on my 12.5" rifle such that it puts my hand in the perfect position to activate my flashlight and IR illuminator/laser, and that had the effect of helping mitigate recoil since I can really pull the rifle into my shoulder without putting my baby wrists in a weird angle. The machining is flawless and the mlok/keymod attachment method is pretty clever. I'm eagerly waiting for a 1913 version to come along.

    These fit tightly and easily on my M-lok handguard and give my an abundance of extra grip for rapid fire precision. This new XOS style is great for covering that extra little space on your handguard on the sides and it really makes a huge difference. I love the Honeycomb it looks beautiful and I would defiantly recommend buying these.

    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.

    Bringing stubbies back in style!

    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!

    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.
