I don't see any use for vertical foregrips, yet they show up on lots of military styled black rifles. What good are they?
Asked and answered. Very well, I might add. With a VFG, mounting the rifle is as simple as, "Putting your dukes up."It's simple ergonomics. Stand up and pretend you are have a rifle mounted. Put your right (if you're right handed) hand on the imaginary pistol grip. Now put your left hand out forward on the forestock barrel. The most natural and comfortable position for your left hand will be pretty much vertical. In that position, you have better ability to control the weapon. You can exert more pressure forward or backward, and are more accurate and quick in side-to-side movement. You also typically have more ability to resist upward movement, such as would be caused by recoil.
