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.

Very solid clamp
This is basically the same clamp as the apex on the Anvil style heads, and I have one on my TFCT-34L tripod. Easily adjustable, and clamps nicely. My only complaint is that for the intended usage of this clamp in PRS and NRL games, the safety on the clamp is really a bit of a negative. I found it easy to remove (along with the R-LOCK plunger, as I don't have any R-LOCK compatible rails), but wish it was available in a non-locking version.

SC ARC clamp
I connected this clamp to a gen 2 ckye pod with the arms 17 head. Fit perfectly and now I can connect the bipod to all 1913 and RRS railed rifles in the safe. Sweet!

Perfect
I have two of these and it’s the best clamp combo out there. Very easy to work with under nightvision. Do yourself a solid put one on your ballhead and one on your atlas bipod. Boom life’s complete.
