An adjustable support apparatus can include a first bracket, a second bracket, and a base coupled to the first bracket. The first and second brackets can be rotatable relative to the base and the second bracket can translate relative to the first bracket. In a first configuration, the first and second brackets can be adjacent one another to retain a device (e.g., a mount, a camera, binoculars, a firearm, etc.) to the adjustable support apparatus. In a second configuration, the first and second brackets can be rotated relative to the base and the second bracket can translate away from the first bracket to release the device from the adjustable support apparatus.
