Engineered for precision shooters and hunters adopting Arca-Swiss style rails on rifles
The RRS® SC-ARC Clamp
for enhanced strength and versatility over Picatinny systems, the SC-ARC delivers dual-compatibility mounting for ARMS-17s bipods and glassing heads.
Dual Jaw for Picatinny and Arca Compatibility
Supports both Arca-Swiss dovetails and Picatinny rails, enabling versatile use with bipods, rifles, or tactical gear, perfect for precision shooters transitioning between rail types.


Seamless Arca Compatibility with RRS Precision
This clamp features an integrated Arca-style dovetail for widespread compatibility with industry-standard quick-release plates, while adhering to the precise 1.5" RRS Dovetail Standard for the strongest, most secure clamp-to-plate connections available.
Rapid Lever-Release with Effortless Top-Loading
Patented lever enables instant, finger-force gear swaps and one-motion top-loading for quick plate insertion from above, boosting your efficiency through extremely fast gear transitions.


Directly Mounts to Bipods
Threads onto A.R.M.S. 17s compatible models like Atlas or Thunderbeast, upgrading them with dual rail mounting capibility that enhances accuracy and reduces wobble during long-range or prone shooting.
RRS-LOCK with Built-In Safety Stops
Features a mechanical safety catch that engages with RRS-LOCK compatible rails to prevent unintended slides or drops, offering peace of mind for military, law enforcement, and hunting applications.


Laser-Engraved Scale for Consistent Positioning
Easily visable markings allow precise, repeatable plate alignment for enhanced consistency in macro, studio, and panorama work.
Enhanced Safety with Visual Lock Indication
The lever's three-position design (closed, half-open, fully open) provides immediate visual feedback on your clamp's status, giving you confidence in your rapid gear swaps.


Low-Profile Lever Prevents Snags
The sleek, contoured lever hugs the clamp body closely without protruding, reducing the risk of catching on clothing, straps, or terrain, enhancing equipment safety in rugged outdoor conditions.

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).

Bipod clamp
As usual, quality is top notch. Very happy with every product from RRS. Enables me to use one biood for both pic rail and Arca.

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
