FUSION was designed to maximize the use of rail space while remaining lightweight and low profile. The hub is constructed from precision milled 6061-T6 aluminum that is then Type 3 anodized in black or FDE for durability. The interface points are very strong and provide for a very rigid mount. The picatinny rail hub has 4 mounting surfaces; a top surface, forward surface, and two wing surfaces. All wing accessories are reversible.
