Fatboy Tripod Leveling Base Kit
This includes a Leofoto YB75LK Leveling Base and Arca Clamp plus the BA-75 Bowl Adapter.
This Leofoto Leveling Base system is the most rigid Arca clamping system available for these Fatboy tripods. The arca clamp allows the rifle to sit much lower to the base of the tripod.
This design also works wonderfully with Spotting scopes and Binos.
