The ARCA Spec Mount QD is compatible with all Accu-Tac current bipods. The ARCA Spec Mount QD is compatible with any standard spec, ARCA Swiss, or ARCA-style rails. It has a new QD lever that will open halfway to slide the bipod across the rail or quickly come off if opened all the way. It will also allow ARCA Swiss rail users to use Accu-Tac bipods without needing an added adapter.
