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.
