The Hannibal Rail variant for the T-1 pattern footprint was developed in response to a request from a state law enforcement agency. They wanted a direct-mount solution that allows the end user to mount any RDS (Red Dot Sight) using the Aimpoint T-1 footprint directly to the Hannibal Rail, placing 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 2″ Picatinny rail and QD swivel mount can be attached to the side of the Hannibal Rail for even more accessory mounting options.
