AP Mach1 Adapter

Bought this so my RST-135 could sit on the same pier plate as my old setup, and it’s dead simple to use. The aluminum feels solid and machined cleanly, no wobble or play when I snugged it down. Exactly what I needed to make the switch without buying a whole new tripod.

Fits like a charm on my Mach1 pier plate, and the aluminum feels rock solid when I torque it down. No wobble at all on my RST-135, which was my main worry before ordering.

Finally got my RST-300 paired with an existing Mach1 tripod, and this adapter made it a perfect fit. The aluminum build feels solid and the threading lined up without any fuss.
