Are you looking for the perfect solution to mounting multiple devices on a single rail? Are you looking for a quick way to attach your Garmin Xero chronograph or Kestrel wind meter to the rest of your RRS system? Do you need to co-witness two optics for fast acquisition of your subject? The Really Right Stuff MPR-CL III is ready for wherever your adventure leads. Building upon the functionality of the MPR-CL II, we have increased the usability and applicability of this multi-purpose rail. Check out all the new features below!

With the use of our patented RRS dual-clamp technology, the MPR-CL III supports mounting to NATO STANAG 4694 Rails (commonly known as Picatinny), opening up a wide range of new applications for this rail.

The addition of (21) 1/4"-20 and (1) 3/8"-16 thru-tapped holes allows the user to customize their rig with a number of accessories, such as our BC-18 or BPC-16 head. The outside 1/4"-20 holes along each dovetail are spaced 9mm/18mm apart down the length of the rail, making it compatible with many popular accessories on the market.

The long slot and custom B105 captive screw can be used to mount accessories to the top or bottom of the rail, such as displays, chronographs, or any product with a female 1/4"-20 tapped hole. Combine this with our MPR-C bar for anti-rotation and indexed mounting.

The fluted lock knob allows for a wide range of travel while also being glove-friendly to use.

RRS-Lock adds another dimension of security to the product when used with RRS-Lock clamps, such as the ARC-LR, SC-ARC or Anvil-30 ARC. The MPR-CL III's RRS-Lock system features ramped end-stops that prevent the rail from sliding off one end, rather than discrete positioning stops such as those found on our USR products.
