Engineered for precision shooters and hunters transitioning to Arca-Swiss rail systems.
RRS® SC-ARC Arca + Picatinny Dual-Compatibility Lever Clamp
The RRS® SC-ARC clamp is a precision-engineered dual-interface mounting solution designed to bridge the gap between traditional Picatinny rails and modern Arca-Swiss dovetail systems. Purpose-built for professional shooters, hunters, and tactical users, the SC-ARC delivers unmatched versatility by allowing direct mounting of A.R.M.S. 17s bipods and glassing heads while also enabling seamless compatibility with 1.5" RRS Arca-style rails. Machined in the USA and built for extreme environments, it provides rapid transitions, absolute security, and uncompromising performance in the field.

Dual Jaw Design for Arca & Picatinny Compatibility
The SC-ARC features a patented dual-jaw architecture that securely interfaces with both Arca-Swiss style dovetails and Picatinny rails. This allows shooters to seamlessly transition between traditional weapon mounting platforms and modern tripod-based support systems. Whether mounting bipods, rifles, or observation gear, the SC-ARC delivers rigid clamping force, zero slop engagement, and dependable repeatability across multiple mounting standards.
Rapid Lever Release with Top-Loading Efficiency
The patented lever mechanism enables instant, finger-force clamp operation and one-motion top-loading insertion. Plates can be loaded vertically without sliding in from the side, dramatically improving speed, safety, and efficiency during rapid transitions. A three-position lever design—closed, half-open, and fully open—provides immediate visual confirmation of clamp status for confident gear handling in dynamic field environments.


Precision-Machined Strength with Built-In Safety
CNC machined from aerospace-grade aluminum, the SC-ARC delivers exceptional structural rigidity while maintaining a compact, low-profile form factor. The integrated Arca-style dovetail conforms to the 1.5" RRS Dovetail Standard for the strongest clamp-to-plate interface available. Built-in RRS-Lock® safety stops and a mechanical safety catch prevent accidental release, protecting valuable equipment in military, law enforcement, hunting, and long-range shooting applications.
Elevate Your Rifle Support System with American-Made Precision
Upgrade your bipod and rifle mounting system with the RRS® SC-ARC dual-compatibility lever clamp. Designed for shooters who demand speed, stability, and absolute reliability, it delivers seamless transitions between Picatinny and Arca platforms while providing the confidence of rock-solid engagement in every shooting scenario.

Works great, love that it works for both picatinny and ARCA

This product is well-designed and well-machined...
This product is well-designed and well-machined and work very well. I own five of these and my girlfriend owns two. The reason I'm only rating them three starts is because the hardware is carbon steel, not stainless, and its finish doesn't last. The main bolt rusts relatively quickly, which is very ugly, and that is simply unacceptable for such an expensive product. I am sick of dealing with corrosion when there's no reason for it. Materials like stainless steel have been available for a long time yet manufacturers would rather make an extra couple of bucks by choosing slightly cheaper materials (kind of a "screw the consumer" attitude).

Really Right Stuff ARCA Pic combo
Pic rail ARCA combo head is absolutely awesome. I've purchased 3 now and ready for another. It's a great option when running both pic bipod and ARCA tripod or any kinda combination. I'm really impressed how smooth this head slides along with the AREA419 rails. It's truly to the best combination I've ever ran. STRONGLY RECOMMENDED THIS SET UP
