What exactly does a vertical grip mean in your world? Is it really just a way to hang onto your weapon, or is it a functional part of your world? Well, for some people a vertical forward grip is just for show. They saw it in a movie and it looks cool. However, when things get real, a vertical foregrip is the real deal.

Hang Onto Your Shorts

In the beginning, a vertical forward grip was meant to give the shooter an anchor point when firing full auto. Now the application of a vertical grip has evolved, depending on your purpose. If you're a three-gun competition shooter, it's a must. If you operate in a CQB environment, you can't live without one. And, if you simply need to have ultimate control of your weapon, it's critical. Whether you're driving your weapon toward the next target or into an enemy’s face, a RailScales RSB Vertical Grip has to be in your hand and under your gun.

Any Way You Want It

Sure, you can live on the plastic. You can find some polymer, wannabe vertical forward grip to clamp onto your rail. But will it be there when you have to have it? The RailScales RSB Vertical Grip is machined out of 6061 billet aluminum. What does that mean to you? It means that you will have your RailScales RSB Vertical Grip to back your play when you need it. This thing isn't huge, it gives you just enough real estate to hang onto and get the job done. The RailScales RSB Vertical Grip is a perfect match for your AR pistol or PDW and it feels right on a carbine-length weapon as well.
