They wanted a direct mount solution that allows the end user to mount any RDS (Red Dot Sight) utilizing the Aimpoint T-1 footprint directly to the Hannibal Rail putting the optic much closer to the bore-line than other mounts. The integrated Picatinny rail on top of the Hannibal Rail is perfect for mounting any additional accessory your heart desires and gives your rifle a more tactical look. The included 2in Picatinny rail and QD swivel mount can be attached to the side of the Hannibal Rail for even more accessory mounting options.
