With over a year of input and development, Cadex is releasing the ARCA Elite System (AES). The AES system is designed for a quick and smooth manipulation that locks up solidly. Using two stainless pins, the AES clamp locks into the precision machined serrations down the center of the ARCA Rail creating a system that will not move, even under the most extreme conditions. This is a huge improvement over the original ARCA design well known to slip under recoil.


  • Rail section that attaches to the chassis fore-end tube.
  • Precision machined from solid 6061-T6 aluminum to the tightest tolerances in the industry.
  • Built to the RRS standard ARCA rail dimensions to ensure all clamping systems work perfectly.
  • Locking serrations are flush to the bottom so they will not interfere with clamping on a tripod.
  • Deep locking serrations for positive lock up and guaranteed not to slip under recoil and loading.



  • Adjustable tension on the AES Clamp for a perfect fit.
  • Machined from solid 6061-T6 aluminum with stainless steel locking pins.
  • The AES clamp can be used on competitors’ ARCA rails by removing the stainless steel locking pins.
  • Cadex’s quick throw lever system for lightning fast manipulation.
  • Attachment of bipods through Picatinny/1913 rail or optional bipod/sling stud interface.
  • All parts are also available separately.
