MAGPUL M-LOK MVG MOE Black Vertical Grip (MAG597-BLK)

This is a solid vertical grip. Medium length, not overly long like many others on the market. Attaches securely to your M-LOK rail and very easy to install. Very light weight also. I typically use it more like a hand stop and do not use it as a full vertical grip. The Magpul and BCM Mod 3 Gunfighter are my top 2 vertical grips, but the BCM is a bit harder to find in stock so I went with the Magpul.

Grip quality is top-notch. Mounts securely, plastic doesn't have any noticeable flex. My only gripe is that you need a long Allen wrench, as the length of the grip makes the head of the screws just a touch out of reach of standard sized hex wrenches.
