Really Right Stuff MPR-CL III Nodal Slide Rail (8")

This 8" MPR-CL III Nodal Slide Rail from Really Right Stuff has an Arca-type double dovetail design that can accept accessories on either the top or bottom of the rail. The rail is compatible with both standard RRS dovetails and NATO STANAG 4694 (Picatinny) rails, unlocking a broader range of applications across photography, videography, and tactical setups. The rail also sports a screw knob-style clamp on one end.

The MPR-CL III rail can be mounted on a ball head, used as a macro slider or focuser, or have an orbital-style flash bracket attached to it. The multipurpose rail offers twenty-one 1/4"-20 threads in a cheese plate layout, with an additional 3/8"-16 accessory socket. There is a laser-engraved scale with 1mm increments on both sides of the rail for precise position repeatability. Additionally, a built-in bull's-eye bubble level helps keep the camera level.
