The best vertical grip - BCM Vertical Grip Mod 3 - KeyMod

Great all around. The identifiable feature that makes it better than most are the contour of the mounting plate area. A lot of other grips are too fat and have too tall of a curve in that area and it makes it uncomfortable for the top-most finger, but this is much slimmer and the finger closest to the handguard never feels like it's being pressured uncomfortably. The angle is also really nice, especially when running the grip in reverse, allowing for a noticeably more aggressive pull on it without having to actually exert any extra energy holding it against the shoulder. I do wish the sides of the mounting area were a bit slimmer so they didn't stick out on handguards with a slim lower rail, and some kind of rubber cap for the bottom so I could store things in it would have been a good addition too. But overall I like it way more than my Magpul grips and at the price it really is unbeatable.
