Really Right Stuff BQDS Rev.C format_16mm and the light seals areThis Really Right Stuff BQDS is a very compact (3. 5x3. 5x1. 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.
