Description
The Magpul RVG (Rail Vertical Grip) in Gray is one of those parts that just makes sense the first time you put your hand on it. It clamps directly to any 1913 Picatinny rail and gives your support hand something solid to pull into, which tightens up your control and makes the rifle feel more manageable when you're moving or transitioning between targets. Molded from high-strength polymer, it tips the scale at just 2.6 ounces, so you get the added grip without hanging weight off the front of your build.
Where the RVG Earns Its Keep
Magpul shaped this grip for two ways of running it. You can hold it like a traditional vertical grip and wrap your whole hand around it, or you can run the thumb-break method that Magpul Dynamics teaches, where your thumb rides up and over the top for a more forward, driven hold. At 3.5 inches tall it sits low enough to stay out of the way, and the aggressive texturing bites into your palm so nothing slips around in the rain, sweat, or gloves.
Setting Up the Magpul Rail Vertical Grip
Installation is quick. Back out the slotted shoulder screws with a flat-head, slide the RVG to the spot on the rail that fits your reach, clamp it down, and you're set. Because the footprint is compact and vertical, it doesn't gobble up rail estate, so you've still got room for a weapon light, pressure pad, or hand stop further down the handguard.
This is a proven piece that shows up on countless AR-15 and AR-10 builds for good reason. It's simple, it's tough, and it's made in the USA. If you want an easy upgrade that improves how your rifle points and handles without complicating your setup, the Gray RVG is a smart, dependable choice.

Frequently Asked Questions
What does the Magpul RVG mount to?
The RVG clamps directly to any standard 1913 Picatinny rail on the bottom of your handguard. It also ships with a universal mounting rail that lets you fit it to many factory plastic handguards that don't already have a Pic rail. That makes it a good match for AR-15, AR-10, and plenty of other long guns.
How do I install the RVG vertical grip?
Installation only takes a couple of minutes with a flat-head screwdriver. You back out the slotted shoulder screws, slide the grip to your preferred position on the rail, then clamp it down and tighten. It's a good idea to check the screws periodically to make sure the grip stays snug.
Is the RVG heavy or bulky on the front of the rifle?
Not at all. The polymer construction keeps it at just 2.6 ounces, so it adds control without weighing down your muzzle end. At 3.5 inches tall with a slim vertical footprint, it also leaves rail space open for a light or other accessories.
Can I run the Magpul RVG with the thumb-break shooting method?
Yes, the grip shape is built with that in mind. You can hold it like a traditional vertical grip or ride your thumb over the top for the thumb-break style taught by Magpul Dynamics. The aggressive texturing helps your hand stay planted either way.
