Introducing the NATO Accessory Mounting Adapter This incredibly small adapter features several options for mounting accessories including a 1/4″-20 and a 3/8″-16 thread, both with locating pins. This Adapter mounts via a NATO connection which allows it to be easily adjusted and locked in place on integrated NATO Rails found on most of our camera cages or via our universal NATO Rail Attachments. Weighing only 30.5g, this accessory is constructed from aluminum alloy and can support a payload up to 3kg.
