Unleash the Ultimate Power

The Cobra System ADDER is already a fan favorite. We pushed it further with the 180 lbs kit,
but now, the evolution is here.- Smaller size, less effort, bigger power.
The all-new “ADDER TX UPGRADE KIT" provides peak performance for your ADDER.

    6.85-INCH|44% NARROWER
    Ultra-Compact Maneuverability

    Navigate tight spaces with ease. ADDER TX UPGRADE KIT reduces your cocked width from 15.5" to an incredibly slim 6.85". It’s narrower, faster, and more mobile.
  • 300FPS|25% INCREASE
    Less Effort. More Powerful

    Compared to the 240 FPS of the original 130 lbs recurve limbs, the new ADDER TX compound cam system hits 300 FPS at the same draw weight.
  • Classic Underlever System

    Inherits the iconic R9/RX underlever cocking system for smooth, low-effort cocking at 130 lbs draw weight.
  • Let-Off Technology

    The compound cam design significantly reduces trigger tension while cocked, extending component lifespan and ensuring a remarkably smooth pull.
  • VULCAN-(5)

    99-130 LBS ADJUSTABLE

    The integrated knob provides stepless adjustment from 99 to 130 lbs, offering unparalleled versatility for all shooter levels.
