Second most comfortable - Watchtower Firearms C7M AR-15 Contoured Handguards

This is a great handguard, only second in comfort to a diamondhead vrs-t. But with the odd dimensions of the diamondhead (less than 1.5" internal diameter) and slanted front (add 1.5" to vrs length) this rail can cover my suppressor and feel great doing it. The section milled for your grip is a perfect distance and like I mentioned super comfortable. The only reason I say second best is because the natural shape (triangular) of the vrs is incredible...but still 5 stars for this unit. Very solid build and install too.
