Timber Creek Outdoor Greyman Vertical Foregrip

Timber Creek Outdoor catalogues this one as the Greyman vertical foregrip, model GVGF.

A vertical foregrip gives the support hand something square to pull against, and that is most of the point. Shooters run a carbine better when the support hand is loading the gun rearward into the shoulder instead of just carrying its weight out front. A vertical grip also indexes the same way every single time the gun comes up, which takes one variable out of the mount. Rail attachment standards vary, so confirm what your handguard takes before ordering.
