KS7-specific dual shell-carrier system built around an extended 15-inch top rail.
Hi-Tech's HTC-105_S1-KS7 combines an extended 15-inch top rail with a dual shell carrier that holds seven shells. The billet-aluminum system is hard anodized and weighs 12 ounces unloaded. Hi-Tech labels it for the KS7 but does not state whether that means Gen 1, Gen 2, or both.
Add the Hi-Tech KS7 7-Shell Top Rail Carrier System (HTC-105_S1-KS7) to your build and see how it enhances your platform.
