This aluminum T-grip for the Rival Kronos is designed by Foam Focus and produced by Worker. When mounting a stronger spring in the Kronos, pulling the slide backwards can get very heavy. With this grip it is a lot more comfortable. The T-grip is CNC milled from aluminum and available with a silver or black anodised surface. Mounting the T-grip is easy. A small adjustment has to be made to the blaster: from the back of the blaster a small piece of plastic has to be cut to make room for the T-grip. Properties of the T-pull Grip for Rival Kronos: ? Strong CNC machined aluminum ? Anodised surface in Silver or Black ? Easy assembly: just cut a piece from the back of the slide ? Designed by Foam Focus, produced by Worker
