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.

SC-ARC
Great clamp. I like it better than the older design of throw lever. The ability to clamp to ARCA or Picatinny isn't the only thing that makes this clamp stand out, it's built extremely well.

Outstanding Rock Sold Clamp
I have an older spec BH-55 Ball Head that was perfectly suited to holding long telephoto lenses and big cameras. However, I no longer shot pictures but instead PRS rifles at insanely long distances. I have two of the Anvil-30 ARC heads and realized the advantage of the locking ARC clamp to secure a 28+ pound rifle. Being able to retrofit my older BH-55 with the SC-ARC and new Rosette adapters allows me to use the great features of that Ball Head with my rifles. As with all RRS/SOAR products everything is top shelf quality and superbly well designed and made. The inclusion in the SC Rosette adapter of longer screws with both thread pitches that RRS has used over the years was a really nice thoughtful touch.
