Very solid and lightweight - Magpul Industries M-LOK MVG Vertical Grip

This is a smaller VFG, but not too small as to be difficult to use. My pinky extends past the bottom of the grip, but with the texture of the VFG and the top of it being concave, I have plenty of grip surface. Especially in view of the light recoil of 5.56, this is a great grip and shave a bit of weight.
