This Really Right Stuff BQDS is a very compact (3.5×3.5×1.25cm) bidirectional Arca- style baseplate. Generally universal, though there is a 3.5mm anti-twist protrusion on one edge, which may get in the way if your camera doesn’t have enough vertical clearance along its baseplate. Despite its small size, this plate features a Magpul QD strap attachment point. In excellent condition.
