Most comfortable angled grip! - Stark SE-5 Express Forward Grip

Bar none, this little handle is ideal and a vast improvement over its competitors. The storage is a bonus, but the shape and angle of the grip is frankly perfect and improves every aspect of weapon handling from shooting to carrying. The texture is just enough...not too harsh and not too smooth. The only drawback was the tendency for the molding process to leave sharp burrs around the front edge of the textured area that can puncture your skin (where your index finger would be), but these can be quickly shaved off with a hobby knife.
